6 FAQs about [Plcs do not contain solid-state components ]
What are the components of a PLC system?
A typical PLC system consists of components like Power Supply, CPU, Memory Unit, Programming Device, Input and Output modules. CPU, Processor or Controller: The operations within the PLC is controlled and processed by a main Central Processing Unit (CPU). It contains arithmetic and logic unit to perform data manipulation and logical operations.
What did PLCs initially replace?
The programmable logic controller, or PLC, was initially designed to replace electromechanical relay systems in order to offer a simpler solution for modifying the operation of a control system. PLCs are ubiquitous in every kind of process and manufacturing industry today.
What is a PLC programming device?
The last component in a PLC system is the PLC programming device. This device is responsible for programming the Programmable Logic Controller. There are two common types of PLC programming devices: handheld programming devices and personal computers (PC).
What are the two most common PLC programming devices?
The two most common PLC programming devices are handheld programming devices and personal computers (PC). Programmable Logic Controllers need to be programmed somehow, and these devices can do it.
