C0 RUN: The IM 308-C reads the input data of the DP slaves
H
cyclically and passes output data to the DP slaves. The IM 308-C
can receive the token from another DP master and pass on the
token.

80 CLEAR : The IM 308-C reads the input data cyclically; output
H
data is set to "0". The IM 308-C can receive the token from
another DP master and pass on the token.
40 STOP: No data is exchanged between the IM 308-C and the DP
H
slaves. The IM 308-C can receive the token from another DP
master and pass on the token.
00 OFF: No data is exchanged between the IM 308-C and the DP
H
slaves. The IM 308-C can neither receive nor pass on the token.
This means that the OFF status cannot be passed on to other DP
masters.
