More functions are added to automation and machine control software seemingly every day. We can do sequencing or logic and motion control and HMI in one software package, on one controller. A common language platform is an essential in most automation software packages these days.
In our July cover story, we wrote that, in many ways, working toward a common environment is as much a frame of mind as it is a software package. Dan Heyman, controls engineering manager for Kuka AT, began years ago trying to get his team members to think in terms of commonizing more functions. "We did this years ago," he said. "We got tired of customizing HMIs to a station. An assembly line can have 60–100 stations on it."
Now Heyman and his engineers use the same function blocks for as many devices as possible. For the most part, they try to stick with ladder logic as a common language. "Some guys just love statement lists. Others can’t read it to save their butts," he remarked. "We try to keep it simple, but try to keep it common, so you don’t have to know multiple languages."
Kuka whittled its function blocks down to around 60, compared with perhaps a couple hundred before. "A lot of that is just discipline in your programming," he says. "We’re giving them the freedom, but also the guidance. Here’s a motion block — do as many different motions as possible, vs. writing one for this cylinder with this particular type of valve."
Similarly, in June we reported on the path that machining center builder Rattunde took to use a single software environment. The CNC, PLC and HMI are programmed within one software environment, noted Richard Stadler, president of Rattunde’s North American operation. "Every end of the machine, every motion, every input, every output is controlled by the integrated control system."

It includes Version Source Control, which provides a means for multiple users to work on the same elements; and Failover, a backup operational mode in which control system functions are assumed by a secondary control system when the primary system becomes unavailable.
RSLogix 5000 v20 software provides a single development environment for CompactLogix, ControlLogix and GuardLogix programmable automation controllers; Kinetix 350 servo drives on EtherNet/IP; and PanelView HMIs. In combination with scalable, right-sized control system components, users can scale from 48 to 10,000 I/O using a single control platform and common user experience.
|The Plot Optimizes
Plot Manager feature of RMCTools software streamlines tuning and optimizing of motion control loops by displaying graphs of target and actual values of motion axis position, velocity, acceleration, pressure, force and other parameters over time. It works with company's RMC70 one- and two-axis motion controllers and RMC150 multi-axis motion controllers. For traceability, reporting and comparison needs, plots can be saved or exported in different file types.

TwinCAT 3 PC-based control software with object-oriented IEC 61131-3 extensions enables programming in IT languages via C and C++. The software modules can run in different languages within a common runtime. Modularity improves reuse of written and tested modules. The runtime operates in real-time conditions with the use of multi-core technology and the support of 32-bit operating systems.
PC Worx RT Basic software PLC, used with an industrial PC, handles control tasks in real time via Profinet, Interbus or Modbus TCP. With a Valueline industrial PC equipped with Intel Core 2 Duo processor, processing times are 0.7 µs for 1K-bit instructions. One core is dedicated to real-time control tasks programmed in all five IEC languages. The remaining core runs existing programs written in a high-level language or other software and hardware under Windows.
