4) Remote RESET
(1) This function permits remote operations to reset the CPU module, which locates in the place where direct operations
cannot be applied, when an error has occurred.

1) For remote function operations, refer to the GMWIN User’s Manual Chapter 7. On-line.
5.6.4 I/O Force On/Off function
1) Force On/Off setting method
Force on/off setting is applied to input area and output area.
Force on/off should be set for each input and output, the setting operates from the time that Force I/O setting enable’ is
set.. This setting can be done when I/O modules are not really loaded.
2) Force on off Processing timing and method
(1) Force Input
• After data have been read from input modules, at the time of input refresh the data of the junctions which have
been set to force on/off will be replaced with force setting data to change the input image area. And then, the user
program will be executed with real input data and force setting data.
(2) Force output
• When a user program has finished its execution the output image area has the operation results. At the time of
output refresh the data of the junctions which have been set to force on/off will be replaced with force setting data
and the replaced data will be output. However, the force on/off setting does not change the output image area data
while it changes the input image area data.
(3) Force on off processing area
• Input/output areas for force on/off setting are larger than the real I/O areas. If remote I/O is specified using this area,
the force on/off function is as just available in it as in the basic I/O areas.
(4) Precautions
• Turning the power off and on changes of the operation mode or operation by reset switch (GM3) does not change
the previous force on/off setting data. They remain within the CPU module and operation is executed with the same
data.
• Force I/O data will not be cleared even in the STOP mode.
• If a program is downloaded or its backup breaks, the force on/off setting data will be cleared. The operating
program in memory differs from the program in the flash memory so that if operation restarts with the program in the
flash memory the on/off setting data will be also cleared.
• When setting new data, disable every I/O settings using the setting data clear’ function and set the new data.
