Interbus 1.1
A device (module) can have the following states:

Alarm Output (bit 0)

Error Output (bit 1)

MAU detection of the incoming remote bus interface (towards data ring)
(bit 9)

MAU detection of the incoming remote bus interface (away from data ring)
(bit 10)

8.6 PCP functionality of the slave
Unambiguous remote addresses are determined for each PCP device in the
higher-level ring for the purpose of managing the services PCP (parameter
data channel) and PNM7 (remote management utility). Unlike the local com-
munication reference (CR) of the lower-level ring (master ring), the remote ad-
dress issued is unambiguous in the network. Each PCP-capable device is
referenced in the higher-level ring by means of the position of the data in the
summation frame protocol. The CRs in the master ring are issued in ascending
order, as a continuous series starting with 2. 2 CRs can be issued for an Inter-
bus controller board: one each for PCP and PNM7.
PCP messages that are evaluated by the driver have the identifier 40xxhex.
Before further processing, the received CR is compared with the preset CR in
the driver to check that they match.
