Dialog box: Set PG/PC interface
tab: Access path
Interface parameterization used:
OK
Note
If the MPI/PROFIBUS interface of the MCI board (X1) is configured in the S7
project as a PROFIBUS interface, we recommend you set the PG/PC interface
of the external computer to "CPxxxx(AUTO)".
The PLC continuously transmits the communication parameters in cyclic
operation, so that the connected devices can adjust automatically.
The default setting of the MPI/PROFIBUS interface of the MCI board (X1) is
MPI. The default setting takes effect after resetting the PLC.
The configuration is loaded from a local SIMATIC 7 installed on the SINUMERIK
840Di sl to the PLC via the default local "SOFTMC" communications link.
The PG/PC interface can be parameterized in the SIMATIC Manager via menu
item: Options > Set PG/PC interface...:
Dialog box: Set PG/PC interface
tab: Access path
Interface parameterization used:
OK
The PLC status and therefore also the communications link to the PLC can be
checked from "HW Config" via menu item: Target system > Status.
– If the current operating status of the PLC is displayed, the communica-
tions link is operating correctly.
– If the current operating status of the PLC is not displayed, the commu-
nications link must be checked for correct parameterization. If no con-
nection is established to the PLC despite correct parameterization, a
general reset of the PLC is necessary.
General reset of the PLC can be performed using 840Di Start–up or HMI Ad-
vanced (option):
