Hardware prerequisites in the PD/OP for accessing the ET 200S
Before you can access an IM 151-7 CPU from a PD/OP, the PD/OP must fulfill the
following requirements:
S it must have an integrated PROFIBUS-DP interface or DP card; or
S it must have an integrated MPI interface or MPI card.
Data transfer rates over 1.5 MBaud require an active connecting cable for the PD
connection.
