With everyone agreed that this was the right strategy to adopt, the replacement started with the HMI and Batch applications phases. These involved a number of separate operations, including collecting Arkema process data (graphic displays, DSR, Templates, etc.), loading the Arkema database into the ABB environment, and further developing the graphic displays, operator interface and batch procedure. Final configuration of the system, e.g. graphic displays, alarms, etc., was done by Arkema.
Next in line was to assess the new architecture and phase it into production.
System 800xA was put on top of Provox and used in production over eight months of standard operations. In Phase 1, both systems were in parallel, with ABB’s in read-only for one month. Phase 2 saw both systems still in parallel, but with System 800xA architecture now being used for standard operation.
Finally, the HMI evolution was completed by transferring all Batch applications to run on System 800xA, and by stopping and disconnecting the old Provue consoles.
