6.2.4 Check PLC status and communication interface
The PLC status and therefore also the communications link to the PLC can be checked from
"HW Config" via menu item Target system > Operating status.
●
If the current operating status of the PLC is displayed, the communications link is
operating correctly.
● If the current operating status of the PLC is not displayed, the communications link must
be checked for correct parameterization. If no connection is established to the PLC
despite correct parameterization, a general reset of the PLC is necessary.
PLC general reset
A general reset of the PLC can be performed using 840Di Startup or HMI Advanced (option):
●
840Di startup
–
Start 840Di startup: Windows XP taskbar: Start > Programs > SINUMERIK 840Di >
840Di-Startup.
– Open the dialog box: Menu command Window > Diagnosis > NC/PLC.
● HMI Advanced (option).
–
Open the dialog box: Operating area switchover > Start up > NC/PLC Diagnosis
● Request general reset of PLC: "PLC Delete Program".
After general reset the PLC is in RUN mode, i.e. the LED "RUN" in the display is green:
6.2.5 First commissioning
On first commissioning of the PLC, a general reset of the PLC has to be performed after the
SINUMERIK 840Di sl has been switched on and booted.
To obtain a defined initial state of the whole system (NC and PLC), the NC data should also
be deleted.
●
PLC general reset
General reset puts the PLC in a defined initial state by deleting and initializing all system
and user data.
● Delete NC data
After a request to delete NC data, all user data are deleted and the system data are
reinitialized on the next NC power-up, e.g. after NC Reset.
