within the determine down below, a consultant P&ID diagram of a jacketed rector, we identified devices and Management modules. Each and every with the five phases controls modes of your corresponding module.
most significant Here's how you cope with these exceptions. one particular exception managing could possibly be To place change the state of a valve to idle or faulty if a malfunction happens.
