A cold start can be initiated as follows:
By pressing the “Reset” button if the operating
mode selector switch is set to “Run M-Reset”,
providing the PLC is currently in the “Ready” or
“Not Ready” status;
By switching on the power supply if the operating
mode selector switch is set to “Run M-Reset”;
By means of the programming software on the
PC provided that the PLC is currently in the
“Ready” or “Not Ready” status.
A cold start is always necessary after a new user
program has been transferred to the PLC.
Warm start
A warm start causes the user program to be
continued from the point at which it was interrupted
to the end of the cycle. The outputs and the
communication data are set to “0” for the remainder
of this cycle. The PLC is then initialized and the
program is executed cyclically. Retentive data fields
remain stored.
The setting of retentive marker ranges is described in
the manual “Sucosoft S 40 User Interface”
(AWB2700-1305GB, chapter 7).
A cold start can also be initiated via the system
parameters if the operating mode selector switch
is set to “Run”. For this activate the Cold Start
option in Behaviour after Not Ready in the
Parameters dialog.
