3.6 Connecting the higher-order controller
Communication with the higher-order controller occurs via
the control connection on the MTR-DCI-... . This connection is
used for infeed and continuation of the fieldbus line.

Tab. 3/7: “I/F” connection (controller connection)
Caution
Device damage with other PROFIBUS devices
When using the separate logic voltage supply via the field-
bus adapter FBA-... (see chapter Accessories) there will be
a voltage of DC 24 V at pin 7.
• Check whether there is any hazard for other fieldbus
stations.
• Observe the pin allocation in accordance with the as-
sembly instructions for the fieldbus adapter.
