The system uses multiple single chip architecture attached toa party line. The control algorithm is based on a two-level hierarchy of decisionmaking,thusthecomplexityisdistributed.A completecircuitdiagramisgivenforthelocalandthecentral station with requirements for the software structure. The design is kept in generalform such that it can be adapted to a multitude of plant configurations.
