Further Notes on FMS
Please note the following:
In FMS server mode, the CP occupies an unconfigured communication bus
connection on the S7 CPU.
Note that the S7 CPU 314 supports a maximum of 4 (newer CPU types a
maximum of 12) unconfigured K bus connections! If, for example, you operate a
PG and an OP with the S7 CPU, two unconfigured K bus connections are still free.
Note
To allow module replacement without a PG, settings on the CPU must be
modified. Open the Properties dialog of the CPU in HW Config; in the “Monitoring
time for...” box in the “Startup” tab, check and, if necessary, increase the following
values:
– “Transfer of parameters to modules”
Depending on your system (station configuration), you may need to increase the
following parameter:
– “Ready message from modules”
