When a PLC is used primarily to replace relays, timers, and counters, it's hard to beat the simplicity and usefulness of ladder diagram programming. Their ability to accept programming in ladder ...

A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and outputs, and makes logic-based decisions for automated processes or machines. 1. The image above is ...

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 ...

Basic Programming for PLCs provides an overview of the basic principles, structure, and instructions of PLC programming. Most PLC programs use instructions written in ladder logic, which is a ...

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, ...

If your usual tools are the Arduino and the Raspberry Pi, you might find it surprising that the industrial world tends to run on Programmable Logic Controllers, or PLCs. You can think of a PLC as a ...

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 ...
