Debugging in Force Mode Section 10-3
10-3 Debugging in Force Mode
I/O tags can be force-set and force-reset in the Program Monitor Window.
When an I/O tag is force-set or force-reset, the I/O status used in the program
is turned ON or OFF regardless of the actual ON/OFF status of the I/O termi-
nals or communications data. This can be used to check the wiring of outputs
and check operation of the G9SP-series Controller even when communica-
tions are not yet connected to enable efficient debugging.
Precautions for Correct Use
• Force-setting and force-resetting can be performed only when the configu-
ration data of the G9SP-series Controller is unlocked.
• Program execution is stopped and the G9SP-series Controller enters the
IDLE Mode when Force Mode is ended or Force Mode times out.
!WARNING Outputs may operate, possibly resulting in serious injury. Take sufficient safety
measures before force-setting or force-resetting tags in the program.
10-3-1 Force Mode
It is necessary to change the G9SP-series Controller to Force Mode to force-
set or force-reset I/O.
Starting Force Mode
You must input the Device Password to change to Force Mode. Force Mode
can be entered only when the configuration data in the G9SP-series Control-
ler is unlocked.
Monitoring Force Mode Time
A limit can be set for the time that the G9SP-series Controller will continue in
Force Mode. The duration time is specified when Force Mode is started or
restarted. The upper limit of the duration time is 24 hours. The G9SP-series
Controller will end Force Mode if the specified duration time elapses.
