Learn about the differences between C++ and ladder logic, two programming languages for PLCs. Find out how they differ in syntax, structure, features, and applications.

Introduction We do a lot of client work with ICS, IIoT, and SCADA. We’ve been to various power plants, factories, electricity substations and they all use the same technology in the form of a PLC. A ...

A Beginner's PLC Overview, Part 4 of 4: PLC Ladder Logic When people ask me what I do, I usually say something like “I work as an engineer for an electrical company”. If they are curious enough to ask ...

Definition – What is a PLC? A programmable logic controller is a computer device used by industrial control systems. They can be used wherever there is a need for control devices, due to the ...

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 ...

Functional logic languages combine the features of both paradigms in a conservative manner. Programs that do not use the features of one paradigm behave as programs of the other paradigm. In addition ...

The PLC Programmable Logic Controller programming is a time consuming task and it needs specific knowledge about the programming language and especially of the PLC, which makes it an expensive work by ...
