IM 253-2DP50 - DP-V0 slave (redundant) - Structure
In principal, the IM 253DPR consists of 2 Profibus DP slave connections.
The two Profibus slaves are controlling the operating modes of each other.
Both slaves have the same address at the Profibus and are communicating
with a redundant DP master.
Both slaves are reading the peripheral inputs. Only one slave at a time has
access to the peripheral outputs. The other slave is passive and in stand-
by. As soon as the active slave is failing, the passive slave accesses the
peripheral outputs.

Please regard to use a redundant DP master for the redundant deployment
of the slave module. Every master unit needs the same parameterization
and bus configuration.
