The project involves modernizing the existing automation system and SCADA system installation in New perlite Unit, S&B ‘s plant in Voudia Milos. The control unit was on a desk and check marks appear in the sign chart, with no possibility of recording events and alarms.

The desire of the client was to be a hybrid system, it could be selected by the operator the ability to control from SCADA, or from the control desk (always through the new PLC), while maintaining the sign chart. Initially, the new CPU was SEND – RECEIVE contacting any current CPU, then the functions of the existing CPU incorporated in the new program.
