Software installation
7. Make settings
7a:
OPI interface (1.5 Mbaud), Configuration: 1 MMC to 1 NCU (on delivery)
Additional settings are not required.
7b:
MPI interface (187.5 Kbaud), Configuration: 1 MMC to 1 NCU (on delivery)
1. Determination of the NCK/PLC bus address
2. Entering the addresses in files
274
– If PLC < software version 3.2,
then NC address = 13
PLC address = 2
– If PLC ≥ software version 3.2 and PLC module 314,
then NC address = 13
PLC address = 2
– If PLC ≥ software version 3.2 and PLC module 315,
then NC address = 3
PLC address = 2
– File "S7CFGPGX.DAT"
In file "S7CFGPGX.DAT" on the MPI driver directory (<installation
path>\MMC2\DRV.ID), the following entries must be adapted to the existing hardware
configuration by means of an ASCII editor:
# Setting the interrupt
"hwint_vector": Setting the interrupt for the MPI card. This interrupt may not be used
by another card (e.g. network adapter).
Default setting: 10.
# Settings for baud rate
"baud rate", "tslot" and "tgap": Settings for baud rate. These 3 settings must always be
activated/deactivated together by removing/inserting the leading "#" (comment).
When the baud rate is changed, the setting "ADDRESS1=\PLC, 10000d01" for 1.5
Mbaud or "ADDRESS1=\PLC, 10000201" for 187.5 Kbaud must also be adapted in
section [840D] in file <installation path>\MMC2\MMC.ini.
Default: 1.5 Mbaud.
