Experimental Digester Batch Control 1996

Objective: Implement experimental digester batch control, develop operator interface.

Requirements: Develop Wonderware operator interface for batch visualization, use Wonderware scripting to implement batch control and coordinate PLC local control.

Results: I have implemented script controlling batch process and allowing to adjust recipe steps. I have also developed easily understandable by operators user interface in the form of log book showing previous, current and following batch phases and allowing to adjust recipes. Software was successfully commissioned in Potlatch paper mill in Cloquette, MN.
