SM251 I/O change flag
OFF : No replacement
ON
: Replacement
• By turning this relay ON after setting the head I/O
number of the replaced I/O module to SD251, the I/O
module can be replaced online (with power on).
(Only one module can be replaced for each setting.)
• Turn this relay ON in the test mode of the program or
peripheral device for an I/O module change during
RUN, or in the test mode of the peripheral device for
an I/O change during STOP.
• Do not execute a RUN/STOP mode change until I/O
module change is finished.
