I am looking for large-scale green field project in gas & oil industry with size of: 15 redundant controllers, about 1500 discreet IO, and 1000 analog IO, 2 eng stations, 4 operator stations, 10 operator touch panels, SIS integrated with SIL2.
I plan to take full advantage of smart field instrumentation, basic and advanced control algorithms with auto-tuning option, object-oriented programming in control and graphic modules, minimum IEC-61131-3 languages, diagnostics and maintenance. The digital communications criteria has high importance. We plan to integrate a high number of subordinated PLCs with Modbus or Profibus DP protocol (depending on which will be cheaper).
I will be thankful for any advice/suggestions.
