Distributed automation system, includes supply connection to special conductors for allocating secured voltages and security connection to conductors which can transmit security signals

摘要

The distributed automation system includes a main module (MT) which can be supplied over a power source, and an operation station (PC) which manages in particular a bus (BC). Machine elements are connected to the functional modules (MF1-MFn) which are connected to the main module via a power connection (B), a feedthrough channel, and the bus. The feedthrough channel includes a supply connection (BA) to special conductors for allocating secured voltages and a security connection (BS) to conductors which can transmit security signals such as the signals of emergency cut-off and/or its own access protection of machine elements.
