Section 1-12
Application
Precautions
• After areas have been enabled using the IOWR instruction (control data =
1838, 183A, 183C, 183E), 0 will be output for the next I/O refresh and the
position data will be output from the following I/O refresh. If the time from
executing IOWR to the first I/O refresh is less than 10 ms, one more cycle
time may be required.
• After words have been enabled using the IOWR instruction (control data =
1838 to 183F) or after changing the word allocations when other words
were previously enabled, the present values will remain in the words that
were previously refreshed.
• When enabled output data areas (A1970 to A1971, A1974 to A1975,
A1978 to A1979, A1982 to A1983) and word data being refreshed in the
CPU Unit are overwritten, the data will be refreshed during the next I/O
refresh period.
• When enabled input data areas (A1972 to A1973, A1976 to A1977,
A1980 to A1981, A1984 to A1985) are overwritten, the contents of the
CPU Unit data words will remain unchanged until the next I/O refresh
period.
• Refreshing will continue even when loads (outputs) are turned OFF by the
CPU Unit.
• Complete setting A1986 to A1989 at least 10 ms before the output for the
stopover function. If the output occurs in less than 10 ms, operation will be
performed with the previous values of A1986 to A1989.

Overview
If this function is enabled, the M Code Reset Bit allocated in the CPU Unit can
be used to reset the M code from the CPU Unit even when program execution
is stopped.
Specifications
Settings
There are no settings required for this function. This function is enabled as
soon as the IOWR instruction is executed to select the customized function.
The following tables show when the M Code Reset Bit is valid.
