Guest contributor: Reinhard Mansius, Bosch Rexroth

Do you ask yourself how to produce smallest quantities in an economically viable manner? That is no problem in the factory of the future: You are able to move your machines within the factory hall or take processing stations out of a production line, reposition them and then continue production at the push of a button. Cabinet-free drive technology is a key technology here with decentralized intelligence and comprehensive communication capabilities.

Looking in any supermarket will reveal promotional packs with twenty percent extra free or special products for Easter, summer, Halloween and Christmas. The product carousel is turning at an ever increasing pace. However, the life cycles of furniture, electronic products and cars are becoming shorter and shorter as well. At the same time, online retail accounts for an increasing share of the market. Consumers like to use online configurators in order to customize their products. As a result of this, you as a manufacturer may have to make production changes several times a week instead of producing the same products over many years. In the future, even this might not be enough and refitting may be necessary on an hourly basis.

On the basis of customer applications and numerous automation projects in our own plants, we have analyzed the requirements of such varied production processes and developed a vision for the factory of the future. Only the ceiling, the walls and the floor of the factory hall will be immovable. In contrast, it will be possible to configure machines and processing stations to create new production lines which will communicate wirelessly with each other. As a result of this approach, control cabinets will be obsolete or will no longer play a central role.

Control cabinets on their way out

The aim in automation: Making production changes primarily via software, with no manual cabling work. With traditional automation concepts, all cables lead from the actuators and sensors to the control cabinet and back again. In practice, this represents a bottleneck when it comes to installation and refitting. In contrast, the IndraDrive Mi servo drives are geared to and integrated into motors. They reduce the amount of cabling work required and take up no space in the control cabinet. They are installed with all necessary supply components in a decentralized manner in the machine or processing station. Up to 30 servo drives form a drive group on a hybrid cable string for power and communication. Only the first drive has an external connection to the higher-level control systems so that changes do not require cabling work on the control cabinet.

Switch off, reposition, switch on and carry on producing

This flexibility is available for a wide power range – from 0.4 kW to 11 kW. The drives without control cabinets have as standard four digital, freely configurable I/O connections for peripherals and sensors on board. Two of these can be used as quick measuring probes. By decoupling control communication, constructors can integrate further I/O modules, sensors and actuators for pneumatics or hydraulics. This means that automation is completely decentralized. As a result, it is very easy to make changes to the factory of the future later on. Simply switch off the station, pull out one or two plugs, push the machine to its new location, switch it on and carry on producing.

Simple, reliable commissioning

You as a machine manufacturer have scarce engineering resources which need to be used efficiently. Pre-defined, pre-programmed technology functions allow many tasks such as those involving cam discs or cam gears to be performed more quickly. With the integrated Motion Logic for individual axes, the drives take on axis-related processes independently of the central control system.

Engineering tools geared to the tasks make integration into modern concepts easier and save time. The Drive System software allows quick and reliable commissioning because its reads and applies the mechanical data from the motor encoders of the Rexroth motors. At the same time, the IndraDrive Service Tool offers easy access to service and diagnostic functions and also allows the software to be parametrized and updated. The tool which is independent of operating systems runs on HTML5-capable browsers and uses the web server which is integrated into the drive. This architecture makes it easier to replace components, while the tool offers practical access management with guest and service rights.

Regardless of the sector – cabinet-free drive technology is revolutionizing mechanical engineering, significantly reducing costs and improving flexibility.

Communicative in a wide range of environments

Another key requirement for the factory of the future is that it can fit into connected environments and share information flexibly. You as a machine manufacturers are looking for drive solutions which allow them to cater for the different protocols in specific regions and sectors with a single item of hardware and thus simplify their entire logistics from ordering to the supply of spare parts. Cabinet-free drive technology meets this requirement with its multi-Ethernet interface. It supports all common protocols via software selection.

Ready for high-level language functions

Bosch Rexroth’s Open Core Engineering software technology allows you to access core drive functions and the integrated Motion Logic alongside PLC automation with high-level language programs.

In the future, you will be able to use Open Core Engineering for Drives to develop or purchase previously unseen web and cloud-based functions in high-level languages. This will establish a link between intelligent servo drive and server- and cloud-based applications. High-level language programming will open up entirely new connectivity options for you. Without complex PLC interfaces, you will be able to digitize the value stream – from recording an order in the ERP system and the MES systems to the drive.

Are you ready for new flexibility?

By modular concepts you will be able to streamline your processes or machines and stations and set them up flexibly and without control cabinet modifications to create new production lines geared to specific order requirements: the factory of the future is an evolutionary process which has already begun. Cabinet-free drive technology is helping you to meet the new requirements as regards flexibility economically, intelligently and safely – today.

SAVING UP TO 90% OF TIME WITH PLC-FREE PROGRAMMING AND COMMISSIONING

Guest contributor, Frank Kaufmann, Bosch Rexroth

However efficient PLC programming for complex tasks may be, it is often relatively time-consuming for simple and moderately complex automation solutions. In light of scarce internal resources, machine manufacturers are looking for ways to speed up engineering and shorten delivery times. A new solution is Sequential Motion Control SMC, a virtually universal technology function for IndraDrive servo drives. It reduces users’ programming and commissioning work by up to 90 percent compared to PLC programming.

Intext

Career portals clearly show the lack of skilled labor: in Germany alone, there are more than ten thousand vacancies for PLC programming and commissioning specialists. The situation is no better in other countries. The lack of skilled labor not only lengthens the time to market for new machines – it also makes it more difficult to develop lucrative services, for example adapting installed stations to new tasks.

If orders are delayed owing to capacity bottlenecks, this annoys customers. This makes it all the more important to come up with an alternative to complex, time-consuming PLC programming. This is where drive-based Sequential Motion Control SMC comes in. It uses the intelligence of servo drives for applications with up to six axes yet requires no external motion control system. The integrated motion control system, on-board I/Os and expandable I/O cards reduce hardware costs and make system integration easier.

Ten automation solutions in the time it would take for one

Lean engineering offers particularly exciting opportunities for machine manufacturers as it allows them to put in place up to ten automation solutions in the time it would normally take for one. As a result, they can step up the pace instantly and ultimately increase their turnover. Independent investigations and empirical findings show that the PLC programming and commissioning work for a flying cutter takes slightly more than a man-week. With SMC, the same result can be achieved in just four man-hours.

With a single command, SMC controls complete motion sequences which the user arranges one after another. These sequences are based on a wealth of automation experience in areas ranging from wood processing to the packaging industry and can cope with simple and moderately complex tasks in a virtually universal manner. With pre-defined commands, users can achieve independent positioning axes, axis and master axis couplings, synchronous axis operation, cam profile applications and sequential movements. Applications range from handling systems, processing stations and test stands to flying cut-off. A wide range of special functions are available: With just a few lines, users can activate head cutting, parts movements, maximum lifting routines, reverse optimization, short length processing and other functions.

Intext2.jpg

90 percent faster engineering – with SMC for IndraDrive, axis couplings, synchronous axes and sequential motion sequences can be achieved much more quickly.

Intext3.jpg

With SMC, users can achieve independent positioning axes, axis and master axis couplings, synchronous axis operation, cam disc applications and sequential movements with pre-defined commands.

Eight commands replace 200 lines of PLC code

When engineering, routine tasks such as defining operating modes, diagnostics and error handling take up significant amounts of time. Up until now, these tasks which are often unpopular accounted for up to two thirds of overall programming time although they barely contribute towards the specific solution. With the SMC option, the drives are pre-configured in the factory, thus eliminating these routine tasks. Thanks to this pre-configuration, users can begin task programming and commissioning straight away.

Sequential programming also helps less experienced technicians to create automation solutions geared to particular applications quickly. A practical example: in an open PLC such as the IEC 61131-3, the programming code for a pair of flying shears is more than 200 lines long. With SMC, the user arranges eight commands one after another and then only needs to optimize the processing procedure. Users merely need to learn around 70 commands. They include complete applications and command up to six axes at the same time with one instruction. Users issue step and motion control commands, use closed-loop force and torque controls and query I/Os.

Intext4.jpg

PLC code with just eight commands reduced to 14 lines. With SMC, programming and commissioning a pair of flying shears takes less than half a day.

Optimizing variables directly

SMC includes a manual mode for setting up and referencing axes, a parameterization mode and an automatic mode for working through the programs. In automatic mode, the solutions can control up to four tasks in parallel. At the same time, a cyclic task allows statuses and diagnoses to be called up at any time. Users can therefore observe and optimize variables while the program is running.

Quick solutions for emerging markets

The level of automation in China and other emerging markets is increasing very quickly at the moment. At the same time, there is a lack of programmers with an expert knowledge of PLC in these countries. With online help, watch-listen and tools for debugging or program management, the free SMC Editor helps even technicians with little experience. If necessary, users can use ready-made templates for visualization or create their own.

Owing to increasingly short product life cycles, rapid automation is also becoming more important in mature markets. Concepts such as Bosch Rexroth’s Factory of the Future are highly flexible and allow the production of very small quantities – even down to a batch size of 1. In the future, end users will be able to adapt their production lines flexibly according to orders at very short intervals and will require new motion sequences and additional processing stations at short notice.

The new processing stations must also fit into connected production lines. As a result, an open system for sharing data and information with other machines and higher-level IT systems is a must. The Sercos automation bus allows real-time cross-communication – an important requirement when it comes to precise synchronization with other process movements. Via software, the user selects in the multi-Ethernet interface one of the common protocols such as Sercos, PROFINET IO, EtherNet/IP and EtherCAT as well as the safety protocols CIP Safety on Sercos, Fail Safe over EtherCat and PROFIsafe on PROFINET.

Another task which only very experienced programmers were able to cope with relates to machine safety. Rexroth’s SafeMotion reduces the time required with certified safety functions. As a result, users do not need any additional safety control system in order to meet the requirements and standards of the Machinery Directive.

Increasing turnover with existing resources

The lack of skilled labor will remain a problem for the global mechanical engineering sector in the long term. SMC is a practically oriented approach for simplifying programming and commissioning. Machine manufacturers can therefore significantly increase the number of automation solutions that they supply even without additional PLC programmers. At the same time, the available specialists can concentrate on automating more complex tasks and here too reduce the time to market considerably.

DIGITAL ASSISTANT REDUCES MACHINE DOWNTIMES

Guest Contributor, Stefan Saul, Bosch Rexroth

Service app makes it easier to diagnose faults and passes on expert knowledge.

Time is money! – This is particularly true when it comes to maintaining machines and systems in factory automation. Every minute that production is stopped costs money – often a lot of money. Maintenance technicians are measured by how quickly they can get a defective machine running again after a stoppage. The challenge: they usually have to deal with machines and systems of various ages and from various manufacturers. The new Digital Service Assistant (DSA) app reduces this complexity and offers quick help when servicing is required. The app allows a maintenance technician standardized, wireless access to the error memory of machines fitted with Rexroth control systems and enables them to contact local service specialists quickly. The app also helps to clearly identify spare parts and order them straight away.

 

Header

An everyday scenario for maintenance staff: a machine operator reports that a machine is not working. In practice, a maintenance worker is alerted and runs to the machine, looking for the cause of the fault on the operating display. Where was the error memory again? Then they find out that the problem is with a drive motor. Now the search begins. Where in the machine is this motor? It is then a case of unscrewing the machine cover, finding the motor and cleaning the name plate. In case of doubt, it may be necessary to remove the motor. The maintenance worker can then return to their office and, with the help of the service hotline for the machine or motor manufacturer, identify the necessary spare part with all options. In many cases, how quickly the machine can be repaired depends on the experience and inventiveness of the individual maintenance worker and how quickly they find the correct information.

Digital access to all information

This is where the Digital Service Assistant comes in. The idea: maintenance technicians using a standard mobile device have wireless access to all relevant error messages and service information for new and installed machines with Rexroth control systems, can contact local service specialists via telephone or Skype, can clearly identify components using a camera and can then order them straight away. As part of a growing digital service portfolio, the app which was developed for iOS and Android devices makes it easier to find and rectify the causes of faults and thus reduce downtimes.

If an error message is received, the maintenance technician logs on to the defective machine from any location via the production WLAN network and reads the error memory. The technician has access to the stored parameters and can see immediately where the problem lies. At the push of a button, they can download the documentation to their mobile device or send it to their e-mail account via a link. In the event of more complex problems, the maintenance technician can call the helpdesk of the control system and drive manufacturer. Geotagging is used to determine where the nearest service centers are and a suitable center can then be selected. If required, the diagnostic information and the unique device identification data can be passed on transparently to Rexroth. Thanks to this precise description of the error, help can be provided quickly because the specialists on the helpdesk can access all the necessary information straight away without having to ask questions or carry out research. On this basis, they can help end users via telephone or Skype in their national language.

Clear identification of spare parts using serial numbers

Identifying spare parts is a common problem for maintenance technicians. With special machines, tailor-made components which differ from the standard designs are often used. And when the components are produced by a number of different manufacturers, the name plate often does not provide the necessary information. To make matters worse, the software version of intelligent modules also plays a role. If the spare part has a different version, this can mean a great deal of extra work. Time-consuming research is often necessary when ordering spare parts or requesting repairs.

This is not the case with Rexroth: for each control and drive component produced, the manufacturer allocates a unique serial number for which a digital twin with all options is saved. Using the DSA, the maintenance technician either brings up the electronic name plate from the control system or scans the QR code or serial number on the component. This information is then sent to the customer portal. Here, Rexroth identifies each component with all options and software versions and the user can order the relevant spare part electronically or request a repair without further questions. This saves a significant amount of time in practice.

Installed in two steps

Users can download the app in the 1st quarter of 2019  free of charge from the relevant app stores and install it on their smart device. Many services can be used straight away even without registering. The service app is also suitable for previously installed machines with Rexroth control systems. Installation requires little work and involves two steps: the control systems must be online via WLAN so that the app can access them. In a second step, the data which may be read out are defined in the machine’s PLC: log book, error memory, operating hours counter and the serial numbers of individual components. As a result, the app is suitable for universal use.

End users always attach particular importance to data security, i.e. security during production. Protecting machines against unauthorized access and manipulation is a matter of top priority. Accordingly, the DSA establishes the connection to the control systems using the internal company WLAN in accordance with IEEE 802.11i. This network is encrypted using the WPA2 key. The app can therefore only read out data that were defined individually beforehand. As a further built-in security feature, it has no write rights for the control system.

Registration optimizes services on offer

The DSA is another building block in Rexroth’s rapidly growing range of digital services. End customers can also register their machines on the customer portal on a one-off basis. As a result of this, the machine data are stored so that service issues can be dealt with quickly and easily by the helpdesk. At the same time, end users themselves can gain an overview of all components used. They receive information regarding relevant service issues such as updates or what they can do to ensure the serviceability of their control systems and drives.

Registration helps Rexroth to optimize its service both regionally and on a customer-specific basis. On the basis of the information regarding the type and number of installed components, the company can put in place suitable service capacities and keep a stock of spare parts.

Part of the OEM service solution

The Digital Service Assistant was specially developed to allow OEMs to integrate it into their digital service concepts. As a modular building block, it fits into manufacturer-specific service tools. Here, OEMs can provide all functions and for example link their own contact data to the geotagging system. If required, Rexroth can remain in the background for the end user and will only update the data stocks and the software.

Modern digital service offerings such as the DSA open up access to all necessary information in order to diagnose and rectify faults quicker than before. They help maintenance staff to find the right solutions more quickly and reduce machine downtimes. They are a further building block for the digital transformation towards the factory of the future.

How to keep prox sensors from latching on

For inductive proximity sensors to operate in a stable manner, without constant “chatter” or switching on/off rapidly close to the switching point, they require some degree of hysteresis.

Hysteresis, basically, is the distance between the switch-on point and the switch-off point when the target is moving away from the active surface. Typical values are stated in sensor data sheets; common values would be ≤ 15%, ≤ 10%, ≤ 5% and so on. The value is taken as a percentage of the actual switch-on distance of the individual sensor specimen. Generally, the higher the percentage of hysteresis, the more stable the sensor is and the farther away the target must move to turn off the sensor.

basic_oper_inductive_sensorBut occasionally, a sensor will remain triggered after the target has been removed. This condition is called “latching on” and it typically occurs when the sensor remains damped enough to hold the sensor in the “on” condition.

Some factors that could cause “latching on” behavior and ways to correct it are:

Having too much metal near the sensor
Using a quasi-flush, non-flush, or extended-range sensor that is too close to metal surrounding its sides will partially dampen the sensor. While it is not enough to turn the sensor on, it is enough to hold it in the on state due to hysteresis. If there is a lot of metal close to the sides of the sensor, a flush-type sensor may eliminate the latching-on problem, although it will have shorter range.

Having the mounting nuts too close to the sensor face
of a quasi-flush, non-flush, or extended-range sensor. Even though there are threads in that area, the mounting nuts can pre-damp the sensor.

Using a sensor that is not stable at higher temperatures
Some sensors are more susceptible to latching-on than others as temperature is increased. This is caused by temperature drift, which can increase the sensor’s sensitivity to metals. In these cases, the sensor may work fine at start-up or at room temperature, but as the machinery gets hot it will start latching on. The solution is to make sure that the sensor is rated for the ambient temperature in the application. Another option: look for sensors designed properly by a reputable manufacturer or choose sensors specifically designed to work at higher temperatures.

Having strong magnetic fields
This happens because the magnetic field oversaturates the coil, so that the sensor is unable to detect that the target has been removed. If this is the case, replace them with weld-field-immune or weld-field-tolerant sensors.

Non-Contact Transmission of Power & Data on Transfer Rails & Grippers

Guest contributor, Stefanie Roedl, Balluff

For press shops utilizing transfer rail systems, fixed sensor connections regularly cause frustration. Cables and contacts are often subject to heavy strain. Cables can wear out and break, damaged pins or mechanical collisions can cause hours of machine downtime, and the replacement of large multi-pin connectors comes at a high cost.

Inductive couplers offer an ideal solution: By using these non-contact, wear-free products you can eliminate pin connections and simplify job changeovers on the press. Inductive couplers transfer signals and power contact-free over an air gap. The quick-disconnect units are easy to use and require no maintenance, enabling you to meet new demands quickly. Mechanical wear is a thing of the past. This increases system availability, reduces cycle time and enhances the flexibility of workflow processes.

Inductive coupling example

Replace pin connections for transfer rails

Typically, two pin-based connectors connect the transfer rail to the transfer system on the press. The connections are on both the feed and exit sides of the rail to the control. If there is any misalignment of the connections, damage regularly occurs. By replacing the connectors with pin-free inductive couplers, the connections are simplified and repair work is minimized. Additionally you don’t have open pins exposed to the environment (dust, water, oil) that can also cause nuisances in the connection process.

Replace pin connections for grippers

To connect the transfer rail on each gripper, normally a pin-based connector is used. As the grippers are changed on each tooling change, the connectors become worn and damaged with regularity. By replacing the pin connector with non-contact inductive couplers, the two sensor signals are maintained but the maintenance of these connections is reduced dramatically. An additional “in-zone signal” verifies that the gripper is installed and connected. This provides assurance during operation.

Inductive couplers offer IO-Link functionality

Inductive coupling with IO-Link technology adds more benefits besides replacing the pin coupling. It allows users to transfer up to 32 bytes of data in addition to power for actuation or sensors. If you connect IO-Link enabled I/O hubs or valve connectors to the remote side, you can also store identification data on the IO-Link hub or valve. When the connection is established, the controller can request the identification data from the tool to ensure that the system is utilizing the correct tool for the upcoming process.

With pin based coupling you needed up to 4-5 seconds to first engage the tool and to mate the two ends of the pin couplers and then request the identification. With inductive couplers, the base only needs to be brought closer to the remote so that you quickly couple and identify the tool before engaging the tool — this takes less than a second. Additionally the base and remote do not need to be well aligned to couple. Misalignment up to 15-20 degrees of angular offset or 2-4 mm of axial offset still provides functionality.

The benefits at a glance

  • Power and signals transfer with pin-less connectivity
  • Reduced downtime due to rail or gripper repair
  • Know that the gripper is present and powered with in-zone signal
  • Inform the controller that the rail has power and connectivity to the sensors

The Evolution of RFID in Metalworking

Guest contributor: Nadine Brandstetter, Balluff

RFID – A key technology in modern production

It’s not just IIoT that has focused attention on RFID as a central component of automation. As a key technology, radio frequency identification has been long established in production. The inductive operating principle guarantees ruggedness and resistance to environmental stress factors. This makes the system highly reliable in function and operation. With unlimited read/write cycles and real-time communication, RFID has become indispensable. The beginnings for the industrial use of RFID go far back. RFID was first successfully used on machine tools in the mid-1980’s. Since the usage of RFID tags on cutting tool holders has been internationally standardized (ISO 7388 for SK shanks, ISO12164 for HSK shanks), there has been strong growth of RFID usage in cutting tool management.

Cutting tool in tool taper with RFID chip

Track-and-trace of workpieces

Modern manufacturing with a wide bandwidth of batch sizes and ever compressed production times demands maximum transparency. This is the only way to meet the high requirements for flexibility and quality, and to minimize costs. Not only do the tools need to be optimally managed, but also the finished parts and materials used must be unambiguously recognized and assigned.

Workpiece tracking with RFID on pallet system

RFID frequencies LF and HF – both RFID worlds come together

In terms of data transmission for cutting tool identification, established systems have settled on LF (Low Frequency), as this band has proven to be especially robust and reliable in metal surroundings. Data is read with LF at a frequency of 455 kHz and written at 70 kHz.

When it comes to intralogistics and tracking of workpieces, HF (High Frequency) has become the standard in recent years. This is because HF systems with a working frequency of 13.56 MHz offer greater traverse speeds and a more generous read/write distance.

As a result, RFID processor units have been introduced that offer frequency-independent application. By using two different read-/write heads (one for tool identification and one for track-and-trace of workpieces) that each interface to a single processor unit, the communication to the control system is achieved in an economical manner.

RFID processor for both tool identification and workpiece tracking

New Hybrid Read-Write Head

Industrial equipment is designed for a working life of 20 years or even more. Therefore, in production you often find machines which were designed in the last century next to new machines that were installed when the production capacity was enlarged. In such a brown field factory you have the coexistence of proven technology and modern innovative equipment. For the topic of industrial RFID, it means that both low frequency and high frequency RFID tags are used. To use both the existing infrastructure and to introduce modern and innovative equipment, RFID read/write heads have been recently developed with LF and HF technology in one housing. It does not matter whether a LF RFID tag or a HF RFID tag approaches the RFID head. The system will automatically detect whether the tag uses LF or HF technology and will start to communicate in the right frequency.

This hybrid read-write head adds flexibility to the machine tools and tool setters as you can use the entire inventory of your cutting tools and tool holders.

RFID Tool ID tag ready for the Cloud

The classical concept of data storage in Tool ID is a decentralized data storage, which means that all relevant data (tool dimensions, tool usage time, machining data, etc.) of a tool/tool holder is stored on the RFID tag which is mounted on the single tool holder. The reliability and availability of this concept data has been proven for more than 25 years now.

With the Internet of Things IIOT, the concept of cloud computing is trendy. All — tool setter, machine tool and tool stock systems — are connected to the cloud and exchange data. In this case only an identifier is needed to move and receive the data to and from the cloud. For this type of data management Tool ID tags with the standard (DIN 69873) size diameter 10 x 4,5 mm are available now in a cost effective version with a 32 Byte memory.

System Perfection – VX25

Guest contributor: Rittal Ltd.

The VX25 is the first large enclosure system capable of meeting the technical requirements of Industry 4.0 to perfection, while at the same time ensuring faster, more productive assembly. This Rittal innovation is the result of our tireless striving for MORE: more simplicity, more speed, more benefits. More than 25 registered property rights confirm the reputation Rittal has earned as the leading innovator in enclosure technology.

vx25

1. Efficient processes

End-to-end, accurate, validated 3D data ensure a high level of planning confidence from the outset. A plausibility check in the Rittal Configuration System facilitates fast, error-free configuration of products and accessories.

2. Reduced complexity

In the VX25, we have managed to successfully replicate all the functions of the predecessor model TS 8 with far fewer accessory parts, while creating new functions and adding value. A consistent 25 mm pitch pattern across all levels and between enclosures has helped to significantly reduce the number of individual parts – for example, 40 per cent fewer punched sections/rails.

3. Improved access

The VX25 is accessible from all four sides, because components can now also be fitted to the outer mounting level from the outside. This saves 30 minutes compared with conventional assembly.  The same applies to the new option of installing mounting plates from the rear.

4. Simple interior installation

Fast assembly is facilitated by complete symmetry on all vertical and horizontal enclosure sides. The installation depth can also be increased by 20 mm with optional accessories. Multiple mounting plates can also be installed in one enclosure.

5. Tool-free installation

The simple, tool-free assembly of the handle system reduces assembly time by 50 percent. Similarly, doors can also be fitted and removed without the need for tools.

6. More functions

Even enclosure accessories can now be built into the base. For example, baying brackets and cable clamp rails can be installed there, and cables can be simply and efficiently retained and secured via the punched sections. Not only does that save time and money, it also boosts safety.
