Weintek has integrated CODESYS and IIoT Gateway into the cMT-CTRL01 – IIoT Programmable Logic Controller. The new model with built-in CODESYS, in addition to working with all iR modules, features IIoT Gateway protocol translation and EasyAccess remote access service, all of which justify its prime role in a smart automation system. With built-in Gateway, cMT-CTRL01 […]
B&R safety controller boosts intelligent safety for mobile equipment
The X90 control and I/O system for mobile equipment is now available with integrated safety technology. Intelligent safety functions and extremely short response times are the key to a whole new realm of possibilities for the safe operation of outdoor plants and mobile machinery. The control system meets the ISO 13849 mobile machinery requirements up […]
What are OSCAT files and how do they relate to CODESYS?
The IEC 61131-3 standard provides a vendor-independent, standardized programming interface for PLCs and automation controllers by defining five programming languages, along with rules for syntax and semantics. Using the languages and structure set out in IEC 61131-3, programmers and developers can more easily and efficiently define and build control software specific to their markets or applications. […]
What are program organization units (POUs) in PLC programming?
The software model for PLCs, as defined in the IEC 61131-3 standard, Programmable Controllers – Part 3: Programming Languages, consists of, at the top level, a configuration. The configuration defines the hardware structure and logic of the PLC system and contains resources (the PLC or PAC, for example), which are able to execute programs. These […]
Why is the instruction list (IL) language for PLCs falling out of favor?
The international standard IEC 61131-3 specifies programming languages for programmable controllers (aka programmable logic controllers, or PLCs), including ladder diagram (LD), structured text (ST), function block (FB), instruction list (IL), and sequential function chart (SFC). Of these, instruction list and structured text are considered textual languages, meaning they use text, numbers, and punctuation — like […]
Control-software portability with IEC 61131-3: How reusable are XML files?
Say an engineering team wants to switch their design’s PLC from one model to another — a relatively infrequent but ordinary specification decision. How well do XML files really work for importing and exporting? How much are component manufacturers really motivated to make that work … and not lock engineers onto one specific hardware? Engineers […]
Opto 22 offers free training with purchase of its pre-integrated GRV-EPIC-LC
Design engineers can get two complimentary seats (a $1,990 value) with the purchase of an Opto 22 groov EPIC Learning Center. The groov EPIC Learning Center (GRV-EPIC-LC) is a pre-integrated system with EPIC hardware and software — suitable for pilot projects, proof of concept (POC) work, and other prototyping and research demonstrations. Hardware in the […]
Programmable automation controllers (PACs) work as an alternative to what exactly?
According to some, today’s most demanding motion designs either incorporate a PAC or industrial PC — and these are engineers’ two leading options for machine control right now. Recall that until recently, industrial automation (including motion control) was extremely segmented. So supervisory control and data acquisition (SCADA) systems were at the system top layer … […]
IEC 61131-3 programming: Where’s structured text more appropriate than ladder logic?
No one IEC 61131-3 language leads for all uses. In fact, the best way to program with IEC 61131-3 languages is by using multiple languages together. That accommodates (among other things) the way every engineer has a different methodology for programming. Sequential function chart (SFC): Recall that SFC is the highest-level code standard in IEC […]
Not just Allen Bradley anymore: New controllers abound
10 years ago, there was one main controller brand in U.S. automation — Rockwell Automation’s Allen Bradley. This is still a leading PLC line with a massive adoption rate in the U.S. because: • Allen Bradley did an excellent job educating people in the U.S. on ladder-diagram programming for its PLCs • The manufacturer embedded […]
