6 PROGRAMMING
If the initial settings for the buffer memory of the intelligent function module on a
remote I/O station are set by a link dedicated instruction (REMTO instruction), write the
program so that when only that remote I/O module is reset (by turning the remote I/O
module power supply off or by using the remote I/O module reset switch), the remote
master station will detect that condition and will once again execute the initial settings
in the intelligent function module.
This program is for resetting the intelligent function module on the remote I/O station
whenever the remote I/O station is reset.

POINT
When the intelligent function module parameters (initial settings) are written to the
remote I/O station, the intelligent function module initial settings are automatically
set, even if the remote I/O station is reset.
