8.18.5 Detecting parallel operation via topology
The topology function is used to detect which transformers are in parallel op-
eration based on the position of the circuit breakers. Each circuit breaker is
fitted with an auxiliary contact so that its status can be reported for this pur-
pose.
8.18.5.1 Topology with fixed master/client
A device (topology master) records the status of the circuit breakers via digi-
tal inputs and reports which devices are taking part in parallel operation to
the connected devices (topology clients) over the CAN bus.

You have to set the following parameters for the topology with fixed master/
client function.
