A Programmable Logic Controller (PLC) is a specialized computing system widely used to control real-time industrial processes and assemblies. The block diagram of a generic PLC is shown in Figure 1.

In Part III of this series, we examined PLC programming methods (ladder logic and functional block diagram), and how the objects (coils and contacts) are system variables stored in the PLCs memory. We ...

The new TML_LIB_X20 Motion Control Library embeds the Technosoft drives’ intelligence into a B&R PLC environment. The library is a collection of high-level functions and blocks allowing the control of ...

This paper attempts a journey right from configuring a PLC, writing application program to code generation along with run-time configurations and RTOS abstraction for embedding it into PLC hardware ...

A human machine interface (HMI) connected to a separate programmable logic controller (PLC) is the standard system for machine automation. However, combining PLC processing and HMI monitoring and ...
