(4) Replacing the RFS instruction
If any I/O numbers targeted for forced ON/OFF are included in the partial refresh
range specified by the RFS instruction, add subroutine calls for P10 and P11 before
and after the RFS instruction. (P10 and P11 are pointers shown in the program
examples in (2).)
If no I/O number targeted for forced ON/OFF is included, addition of subroutine calls
for P10 and P11 is not necessary.
(a) When partial refresh for input (X) is executed by the RFS instruction
Add a subroutine call that executes forced input after the RFS instruction.
(b) When partial refresh for output (Y) is executed by the RFS instruction
Add a subroutine call that executes forced output before the RFS instruction.
(5) Restrictions
Replacements described in (2) to (4) do not apply in the following cases:
• Input and output targeted for forced ON/OFF are referred or changed using the
direct input device (DX)/direct output device (DY).
• Input and output targeted for forced ON/OFF are referred or changed within an
interrupt program.
A subroutine call that executes
forced input is added.
A subroutine call that executes
forced output is added.
