ABSTRACT:
The control and protection assembly according to the invention comprises several channel units, for example a motor channel unit, a jack channel unit and an inputs-outputs channel unit, directly connected to the process to be controlled, each unit comprising a microprocessor preprogrammed so as to perform control, decentralized protection and monitoring of the associated channels. Each unit is connected to an electrical power supply system and to an internal serial network. A connecting unit acts as interface between the internal serial network and a local area communication network. The configuration and parameter setting information relevant to the process to be controlled is supplied to the various units by means of a console connected to the connecting unit.
