SINUMERIK 840Di sl Manual (HBIsl) – 01/2007 Edition
To load the configuration into the PLC select the following menu item: Target
System > Load in Module.
The dialog box for loading the configuration now displayed offers the following
options:
– Set the PLC to the operating status STOP. See note below.
– Compress the memory if not enough contiguous free memory is avail-
able
– Reset PLC to operating status RUN
Note
When the PLC program is loaded in the RUN operating status, each block
loaded becomes active immediately. This can result in inconsistencies when
executing the active PLC program. You are therefore advised to place the PLC
in the STOP state before loading the configuration.
The STOP condition of the PLC which is taken by the PLC for a short time
on loading is interpreted by the NC as a PLC failure with an appropriate alarm
response.
Once the configuration has been loaded you must therefore initiate an ”NC
Reset”, for example, via the ”840Di–Start–up” user interface. In ”840Di–Start–
up” select menu item: Window > Diagnostics > NC/PLC:
Dialog box: NC/PLC Diagnosis
Group box NC
Button: ”NC Reset”
