Multipoint Interface (MPI/DP)
You can connect your PG 740 to a SIMATIC S7 programmable logic
controller using the floating MPI/DP interface. The MPI cable for connection
to SIMATIC S7 CPUs is supplied with the PG 740 (Order No.:
6ES7901-0BF00-0AA0).

Multipoint Interface
You connect your PG 740 to a SIMATIC S7 programmable controller as
follows:
1. Switch off the PG 740.
2. Open the cover over the interface ports on the left-hand casing side panel.
3. Plug the connecting cable into the MPI/DP port.

Caution
Risk of damage to the PG 740!
Before plugging the cables in, you must discharge your body’s electrostatic
charge by briefly touching a grounded object (ESD guideline).
Via the MPI/DP interface, you can couple your PGs to the S7-200, S7-300
and S7-400 programmable controllers, and also to the PROFIBUS DP
(limited extent).
