Old habits die hard. But change is inevitable. And in this case, if proponents are right, change is on the way in the form of an open PLC programming standard known as IEC 61131-3. Promulgated by the ...

As engineers, we often need to design a customized control system or interface to address a need which can”t be met with an off-the-shelf interface device. In the used-to-be days, we”d get a Bud box, ...

THE use of function blocks for programming of programmable logic controllers (PLCs) is gaining wider acceptance. Rather than the classic “contact and coil” representation of ladder diagram or relay ...

STÄUBLI TEC-SYSTEMS is launching the uniVAL pi software that will allow robot programming to be implemented via the PLC, using Plug & Play in Siemens TIA Portal. Thanks to this optionally available ...

A three-day training program for automation technology and IEC 61131 programming will occur on five separate dates in 2016. A three-day training program for automation technology and IEC 61131 ...

A PLC or programmable logic controller is a type of computer often employed to monitor and control industrial manufacturing operations. The device, which you may see referred to as a programmable ...

It’s surprising how much of an impact such a small component as a programmable logic controller (PLC) can have on the smooth operation of a hyperscale data center. While people rarely see it, the PLC ...

Programmable logic controllers (PLCs) traditionally have been considered inherently insecure. But a new security initiative that outlines 20 best practices for coding the industrial computing device ...

There are various approaches to developing programmable logic controller (PLC) applications using experimental techniques. Modifying existing PLC ladder logic programs is another common approach ...
