If a communication converter is used, the device and the communication converter are
linked with a FO5 module via optical fibres. The converter itself is equipped with
different interfaces for the connection to the communication network. For ordering
information see Appendix A, Subsection A.1.1, Accessories.

Examples for communication connections
Disturbance and
Transmission Fault
The communication is continuously monitored by the devices.
Single faulty data telegrams are not a direct risk if they occur only occasionally. They
are recognized and counted in the device which detects the disturbance and can be
read out as statistical information.
If several faulty or no data telegrams are received, this is regarded as a data
disturbance
in the communication as soon as a time delay for data disturbance alarm
(default setting 100 ms, configurable) is exceeded. An alarm is output. When the
system offers no alternative way of communication (as for the ring topology), the
teleprotection scheme is disabled. As soon as the data transmission operates properly
again, the devices will automatically switch back to the teleprotection scheme.
Operating time jumps that, for example, can occur in case of switchings in the
communication network can be recognized and corrected by the device. After at least
2 seconds the operating times are measured again.

Note:
The redundancy of different communication connections (for ring topology) requires a
consequent separation of the devices connected to the communication network. Dif-
ferent lines should not be conducted via the same multiplex-card, as there are no oth-
er lines which could be used instead when the card failed.
