SINUMERIK 840Di Manual (HBI) – 06.03 Edition
Before loading the configuration (system data blocks) into the PLC, first the re-
quired MPI connection must be established.
If the configuration is transferred from an external PG/PC (e.g. PG740), the fol-
lowing requirements must be fulfilled:
S
An MPI card exists (e.g. CP5611)
S
The MPI drivers are installed
S
Current interface parameterization: CP5611(MPI)
S
Data transfer rate: 1.5 Mbps
S
The MPI interface of the PG/PC is linked with the MPI interface of the MPI
board (X111) using an MPI cable.
If the configuration is transferred from the PC in which the MCI board is installed
(e.g. SINUMERIK 840Di with PCU50), the following requirements must be ful-
filled:
S
The MPI drivers are installed
S
Current interface parameterization: SINUMERIK MCI board (MPI)
S
Data transfer rate: 1.5 Mbps
Parameterization of the MPI interface is carried out with the SIMATIC Manager
using menu command Tools > Set PG/PC Interface.
Dialog: Setting the PG/PC Interface
Register: Access Path
Interface parameter set used:
with ext. PG/PC: CP5611(MPI)
or
with local PC: SINUMERIK MCI board (MPI)
Button: “Properties”
Dialog: Properties
Group: Network Parameters
Transmission rate:
1.5 Mbps

OK
Note
Parameterization of the MPI interface can be effected or changed from the
SIMATIC Manager at any time.
The PLC status and thus also the MPI connection to the PLC can be checked
from “HW Config” using the menu command Target System > Status.
