   What are the parts of a PLC?

   • A PLC will consist of two basic sections: the central processing unit (CPU) and the Input/Output (I/O) interface system. The CPU controls all system activity primarily through its processor and memory system. The CPU consists of a microprocessor, memory chip and other integrated circuits to control logic, monitoring and communications.

   What are PLC systems?

   • Now we’re going to look at PLC systems, what they are and why they might be used. What is a PLC? PLC stands for “programmable logic controller”. They are used to automate industrial processes as they can operate in extreme environments. These environments can include extreme temperatures, dusty conditions, or wet conditions.

   How did PLCs work?

   • Before PLCs, control was carried out via banks of relays. Each relay controlled dedicated inputs and outputs based on physical wiring. Relays would control other relays to form logic controllers. For example with a simple AND gate, only when 2 inputs are energised, this one AND this one, does the relay output energise.

   What is a large PLC system?

   • Large PLC systems consist of a rack into which circuit “cards” are plugged. These cards include processors, input and output (I/O) points, communications ports, and other functions necessary to the operation of a complete PLC system. Such “modular” PLCs may be configured differently according to the specific needs of the application.
