Programmable Logical Controller (Plc) 2
Programmable Logical Controller (Plc) 2 : A solid state control system which has a user programmable memory for storage of instructions to implement specific functions such as: I/O control logic, timing, counting arithmetic, and data manipulation. A PLC consists of a central processor, input/output interface, memory, and programming device which typically uses relay equivalent symbols. The PLC is purposely designed as an industrial control system with can perform functions equivalent to a relay panel or a wired solid state logic control system
