How to Test PLC Analog Output

Overview of PLC Analog Outputs  A Programmable Logic Controller (PLC) is a compact computer-based industrial control system that uses input/output(I/O) modules to control processes, machines, equipment, and other control modules. A PLC receives various types of electronic and electrical signals. It uses the received signals(input) and its programmed logic to monitor and control the outputs […]

Common PLC CPU Failures

PLC’s CPU Functions Programmable Logic Controllers are digital electronic devices that are mainly used as industrial control systems. PLCs contain a programmable memory that stores a series of user-defined instructions. They function by continuously monitoring the state of input devices and executing the stored program logic so as control the state of connected output devices. […]

What is the Difference Between Digital and Analog Inputs in PLCs?

PLC Inputs Overview   PLC controlled systems have become the backbone of almost all industrial automation processes globally. A PLC collects data from field devices, processes it as pre-programmed, and passes it as output to another system. To accomplish this, PLCs are equipped with sophisticated electronic input modules (for collecting field data) and output modules (for providing […]
