The configuration of the program control system of condensate polishing system, make-up water system, integrated water system, coal transportation system and ash system is basically the same, but the number of I / O points is different. The typical configuration diagram of the power plant coal transportation program control system is shown in the following figure:
This system includes control-level industrial Ethernet and field-level PROFIBUS network. A total of 2 operator stations are configured, one of which is used as an engineer station to configure and program the system, and is used as an operator station after completion. The controller uses the S7 400H system and is connected to the operator station via industrial Ethernet.
I / O adopts remote I / O and is connected to the controller S7400H through PROFIBUS. In order to ensure the communication rate of long-distance communication, a repeater is added to PROFIBUS to amplify the signal.
