Master redundancy

It is possible to start the DP master in redundancy mode in order to assemble a redundant control system. In
this case, the DP master only listens to the bus, but is not active on it.
To assemble a redundant control system, two masters are on the PROFIBUS (both have identical
configurations): the primary master, which performs communication under normal circumstances, and the
redundancy master, which only listens to the bus without transmitting. The only difference in the PROFIBUS
configuration between primary and redundant master should be in the settings Redundancy Mode and
