Communication via point-to-point CP on the ET 200M
Connection via ET 200M
Links from fault-tolerant systems to single-channel systems are often possible only by way of
point-to-point connections, as many systems offer no other connection options.
In order to make the data of a single-channel system available to CPUs of the fault-tolerant
system as well, the point-to-point CP, i.e., CP 341, must be installed in a distributed rack
along with two IM 153-2 modules.
Configuring connections
Redundant connections between the point-to-point CP and the fault-tolerant system are not
necessary.

switched PROFIBUS DP
