S7-200 (Note: 19.2 Kbps only)
Only 19.2 Kbps for S7-200 in MPI Subnet
Note
At 19.2 Kbps for communicating with S7-200,
– a maximum of 8 nodes (CPU, PD/OP, FM/CP with own MPI address) is
permitted in a subnet, and
– no global data communication can be carried out.
Please consult the S7200 Manual for further information!
Removing and Inserting Modules in the MPI Subnet
You must not plug in or remove any modules (SM, FM, CP) of an S7-300
configuration while data is being transmitted over the MPI.
Warning
!
If you remove or plug in S7-300 modules (SM, FM, CP) during data transmission
via the MPI, the data might be corrupted by disturbing pulses.
You must not plug in or remove modules (SM, FM, CP) of an S7-300 configuration
during data transmission via the MPI!
