2) Special data register for forced I/O set
The contents of forced I/O setting is registered to special data register as below.
It is possible to use ‘forced I/O function’ to program.

Forced I/O enable by bit
D4700 ~ D4731
Forced I/O set data
D4800 ~ D4831
3) 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 wh
ich have been set to force on/off will be replaced with force setting data to change the input image are
a. 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 w
ith force setting data and the replaced data will be output. However, the force on/off setting does not c
hange 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 (K1000S) do
es 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 oper
ating 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.
