Description
1TGE120021R0010 Redundant Control System
The 1TGE120021R0010 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.
1TGE120021R0010 adopts remote i/o mode, according to the actual number of i/o points configured two 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.
