1. Open loop control system 2. Closed loop control system (a) The Open Loop Control System: A block diagram of system is shown an open loop system is shown in Figure. An open loop control system is that in which the control action is independent of the system input. Loop Diagram Symbols and P&IDs This P&ID diagram illustrates the use of software data links between controllers. These controllers communicate over a communications bus and pass variables back and forth between the IOP (input output processor) sections of the DCS. The communications processor will then put the information in Communication is about transmitting messages between the sender and the receiver. The communication loop that we are going to describe here, is universally acceptable in that it applies equally well to all forms of communication - verbal and non-verbal, direct and indirect, and written and oral.
