8.2 Bus connection and termination
The PROFIBUS-DP bus termination consists of a resistance combination ensuring a defined
zero potential on the bus.

8.3 PROFIBUS-DP bus cable
In the IEC 61158, two bus cable types are specified. Cable type "A" may be used for all transfer
rates up to 12 Mbps. Cable type "B" is outdated and should not be used any longer.

The following table specifies the PROFIBUS connectors used within HIMA.

Note When using the F 8628X Ethernet interface (e.g. for ELOP II TCP), the
straight PROFIBUS connector should be utilized. An angled connector
might have to be removed to reach the F 8628X Ethernet interface.
