Part 6: IDE and other software for connectivity and IoT design work

By Lisa Eitel | June 10, 2020

As mentioned in Part 5 and at the top of this series, software that unifies various aspects of automation development is key to IIoT connectivity. Such software typically provides what’s called a universal engineering environment or more commonly an integrated development environment (IDE) to let engineers connect machinery with IT and other facility architectures. In fact, IDEs can also help minimize downtime — the primary enemy of most manufacturing, packaging, and processing.

“Changeovers especially degrade throughput. But as Industrie 4.0 concepts become more widespread due to consumer demands for greater customization and personalization, changeovers are becoming more and not less frequent and necessary,” says Jeff Johnson, mechatronics product manager of Beckhoff Automation.

In practice, this is where IDEs really shine — in rendering automated installations both modular and scalable. That’s illustrated by Lenze’s Plug & Produce software structure mentioned earlier — which makes machine modules capable of coupling automatically and self-coordinating when being joined or rejoined with alternative production-line arrangements.

Cyber dynamic products from WITTENSTEIN include an array of motor, gearmotor, and linear components — including the one shown here. The devices have full ac servo motors and are very compact — with frame sizes down to 17 mm. Modern digital feedback and single-cable connectivity simplify integration. Configuration software on ePLAN.de helps simplify mechanical and electrical design work.

But another strength of standardized IDEs is how they can facilitate the integration of more exotic automation equipment. Consider linear-motor conveyors — also called intelligent transport systems or linear transport systems. Programming for Beckhoff’s linear-transfer system called XTS is relatively simple in part because the XTS can be setup with the same TwinCAT software and EtherCAT network as standard machine controllers.

Johnson cites that as a relatively new option for flexible automation that’s heavily reliant on software for advanced functionalities.

“Through the implementation of a modular mechatronic transport system in place of inflexible mechanical components, manufacturers can eliminate downtime for changeovers while enabling asynchronous processing. Using our software, program changes can happen on the fly … and in cloud-connected smart factories, machine builder OEMs or offsite engineering staff can remotely execute updates.” The system’s modularity and customizability facilitate rapid changeovers and flexible mass production — down to lot sizes of one, adds Johnson.

Engineers don’t have to learn an entirely new programming platform … and in fact, the software’s motion-control library offers myriad preprogrammed functions for XTS — such as point to point, NC, gearing, camming, and flying saw … along with built in collusion avoidance, notes Johnson.

Yet another feature of the software — integrated into Microsoft Visual Studio — is that it allows programming via IEC 61131-3 languages and computer-science standards.

Shown here is an eXtended Transport System (XTS) from Beckhoff.

Other automation vendors see value in the same accommodation of a widening array of programming languages. For example, WAGO’s controllers combine established IEC 61131-3 programming methodology (WAGO e!COCKPIT IDE software) with the option of adding newer technologies better suited to IIoT applications. That’s also true of Bosch Rexroth’s new ctrlX AUTOMATION platform, which accommodates IEC-61131 along with programming languages having both established and newer presences in automation applications — such as PLCopen, C/C++, Node-Red, Python, Blockly, Java, and G-Code.

All this software standardization imparts benefits that are synergistic with the line-blurring multi-function hardware formats such as the gateways, HMIs, controllers, and motors described above — which don’t rigidly tie set machine functions to specific components.

For example, a new line of Weintek cMT X series HMIs allow data display and storage, machine control, PLC communication, protocol translation, alarm notifications, media playback, and IIoT integration. Connectivity includes that via RS-232, RS-485 2W/4W, CAN Bus, Ethernet 10/100/1000 Base-T × 1, and Ethernet 10/100 Base-T × 1.

Here’s an example of a component that’s not rigidly tied to set machine functions. This is a Weintek cMT3162X oTP touch HMI — one of three new cMT X series HMIs. Capabilities include display and storage, machine control, PLC communication, protocol translation, alarm notifications, media playback, and IIoT integration. A powerful Cortex-A17 quad-core CPU makes for a user experience that’s much like that of a smartphone or tablet. The processing power lets users leverage Weintek’s cMT HMI + CODESYS offerings and even run CODESYS and complex graphics simultaneously. Peripheral connectivity includes dual Ethernet ports, RS232 and RS485 2W/4W, CAN bus communication ports, a USB Host port, and built-in mono speaker.

Shown here is a Lenze c550 controller that imparts Industry 4.0 functionality to automated installations necessitating high performance and IT-OT connectivity. It even works in applications for which only industrial PCs worked in the past. “We want to free OEMs from worrying about whether the controller can deliver sufficient computing power for complex tasks. The c500 series has enough,” says Martin Kluge, head of product management automation systems at Lenze. The c500’s Intel CPU is the most powerful of its kind to handle the rapidly increasing requirements of general IIoT control tasks and motion applications. The ability to omit an industrial PC reduces programming and connectivity effort … and the controllers let machine builders use Lenze’s FAST Toolbox standard software modules as well as modules developed in-house. Existing programs and program modules written in standard IEC 61131-3 systems can also be reused.

“Similar to the expansion of PLC functions, microcontrollers are also becoming less and less micro … because the Raspberry Pi and similar offerings along with smartphones and tablets are capable of astounding computing power for a low price — so have revolutionized how we in industrial automation think about computing,” explains Tubbs of Bosch Rexroth.

In short, the dominant value for consumer products has moved from the hardware to software. Now (with the typical adoption lag of manufacturing) industrial computing is finally seeing the same trend. After all, industrial-automation processors today can reside almost anywhere — in standalone housings, inside a drive, or on a motor. What’s more important is what runs on the processor. “In our new platform, we run on hardware and scale via software to simplify the maintenance of parts and replacements. Applying functions is as simple as downloading the necessary software — just like on a smartphone,” Tubbs adds.
