PFEA112-65 3BSE050091R65 Redundant Control System

PFEA112-65 3BSE050091R65 includes two 414-4hcpu, two redundant power supply templates, and two redundant cp443 NICs. One cpu (main) participates in the control during normal operation, and the other cpu (spare) is synchronised with it through the synchronisation module. When failures of the main cpu, rack, power supply, communication, etc. are detected, the spare cpu is immediately put into control without affecting the continuity of the production control.

PFEA112-65 3BSE050091R65 adopts remote i/o mode, according to the actual number of i/o points configured with 2 et200m intelligent remote i/o station, remote intelligent i/o station and controller using redundant profibus bus communication. The decompression control station selects siemens s7-200 plc control system, and installs human-machine interface for local operation and setting relevant parameters. Decompression control station using em277 and gas cabinet control station to achieve network communication, gas cabinet control station for the system master.

PFEA112-65 3BSE050091R65 the whole system network is divided into field level, control level, monitoring level three levels, the system network structure is shown in Figure 1. field level using profibus dp redundant fieldbus for communication, mainly to achieve s7-400h master and remote intelligent slave between the data transmission, the use of Siemens twisted pair cable transmission rate up to 12mbps.
