9.1 What to Do If Something Unusual Occurs (GT10)
Solution
Set the F bit to OFF on the PLC side.
(Do not use the basic communication
area with ladder programs.)
Perform correct bit operations on the
PLC side. (Do not use the basic commu-
nication area with ladder programs.)
1) Confirm that the screen transfer cable
is correctly and firmly connected.
2) Connect to TOOL port with screen
transfer cable.
1) After confirming the safety of the de-
vice, etc., turn off the power supply
and then turn it on again. The GT10
CPU will be reset.
2) If 1) produces no change, bring up the
system menu and initialize the
memory (F - ROM), then transfer data
again from GTWIN to the GT10.
CAUTION:
When doing this, all base screen data,
GT10 setting data, keyboard screen
data, and bitmap data will be lost. Be-
fore doing this, make sure all data has
been backed up.
3) If 2) produces no change, set the op-
erating mode setting switches 2, 3 and
4 on the rear of the GT10 to ON and
reset the power supply.
CAUTION:
When doing this, all of the contents will
revert to those in effect at the time of
shipping, and all of the GT10 memory
contents will be cleared. Before doing
this, make sure all data has been
backed up.
