control system |
摘要 |
Control system for controlling safety-critical processes with communication over a field bus. The inventive system has the control unit integrated in the interface module, i.e. the multi-port memory interface of the bus master. Thus it is not directly connected to the field bus and can insert fail-safe data without a security protocol relevant interpretation in the field bus frames prior to transfer of the data to the signal unit.
