Plc Architecture Block Diagram. It has three major units sections. The central processing unit is heart of plc.
The fig shown the block and circuit diagram of output module. The input section converts the field signals supplied by input devices sensors to logic level signals that the plc s cpu can read. The cpu processor also exchanges data with the program and data memory.
The central processing unit is the heart of the plc system.
Block diagram of plc plc system layout. The central processing unit is heart of plc. The fig shown the block and circuit diagram of output module. The plc has following basic sections are processor section cpu the processor section is brain of plc which consists of ram rom logic solver and user memory.
