Digital output assembly, automation device and decentralised automation device with predefined output states

摘要

the invention relates to a digital ausgabebaugruppe (bg) with a host interface (b), which schaltmittel (sa, sb, sn) and a processing unit (ve) value.the processing unit returns a specific anlaufzustand (sz) in the absence of a data communication to the host interface to a schaltmittel, a arbeitszustand (ab) in a schaltmittel, which was received at the host interface, and a specific ausfallzustand (a z) in interruption of data communication to a schaltmittel.this is the advantage that, in order to achieve the minimum equipment and fertigungsstandzeiten vorgebbare ausgabezustu00e4nden (sz, az, nz) in fehlerfu00e4llen and operation can be spent.as schaltmittel can a monostabiles circuit element (tc) with an additional ansteuerbares bistabilen circuit element (br) are used, which notfallzustand (nz) in the event of the power outputs. so can the set schaltposition (sp1, sp2) of the bistabilen schaltrelais a schaltzustand the burden for the notfallzustand are determined.
