PLC side. (Do not use the basic commu-

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 GT30
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 GT30.
CAUTION:
When doing this, all base screen data,
GT30 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 GT30 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 GT30 memory
contents will be cleared. Before doing
this, make sure all data has been
backed up.
