摘要：for the transfer of datensignalen between steuerein\richtungen (suo, ra;...;took, la) of a ringleitungs\systems (ringo, rignl) in each of the control devices of asignalbehandlungseinrichtung (mp, mem), which the transferred data signals with the aidof at least d a datensignalblock assembles a addressee.this
signalbehandlungseinrichtung is a sendepuffer - arrangement (sp) with a
durchlaufspei\cher (fifol) downstream. in this durchlaufspeicher is prepareddatensignalblock assimilated.with the durchlaufspeicher is a puffersteuereinrichtung (ps)connected to receive a control unit, which control unit assigned to
sendeberechtigungssignals a wortweises reading of the durchlaufspeicher registereddatensignalblocks allows.in addition, adds the puffersteuereinrichtung prior totransmission of the received sendeberechtigunssignals to the leer\zustand ofdurchlaufspeichers anzeigendes signal a senderadresse) the end of a datensignalblockeskennzeichendes endekriterium to the currently assigned datensignalblock.
