The DIAGNOSIS, START-UP and GENERAL RESET MODE softkeys are used
for selecting the GENERAL RESET MODE basic display.
Functions in GENERAL
RESET MODE
Required only for changing operating system of NC and PLC. This softkey initia-
tes an identifier for NCK and PLC which results in subsequent booting.
CAUTION! Booting is started automatically after the next POWER ON-RESET
(e.g. END GENERAL RESET MODE). Then a general reset of the NCK and the
PLC is to be carried out.
The PLC user memory is deleted and any existing user program is copied from
the hard disk to the PLC. If the PLC is to be cleared, the ANW_PROG program
must previously be deleted on the hard disk. More than one PLC program can be
managed under SERVICES, however, ANW_PROG is the only program to be
loaded in the PLC during general reset.
The cursor keys are used for selecting the toggle fields.
The selection key is used for selecting the objects to be deleted.
Formats the user memory of the NCK. The data areas to be formatted can be se-
lected individually by means of the YES/NO toggle fields. The default setting is
“YES”.
