InterBus-S Interface X73 (ZS550-DP-IBS only)
With the ZS550-DP-IBS, the decentralized peripherals can be connected via
the DP/V1 master interface and also via an InterBus-S master interface. The
data exchange with the decentralized bus stations (slaves) is cyclic. I.e. that
the master reads the input information from the slaves and writes the output
information to the slaves. The master itself sets the transfer rate. The master
starts a test run of the bus, one with 2 Mbits/s and another with 500 Kbits/s.
The bus shall continue on the transfer rate on which the bus runs without
error.
The InterBus-S interface is not galvanically isolated. By using the IBS optical
fibre adapter IBS OPTOSUB-MA/M/L-LK by Phoenix Contact (not included
in the delivery), a connection to an optical fibre InterBus-S system is possible
as well.
