SM210
Clock data set
request
OFF : Ignored
ON : Set request
Clock data stored in SD210 to SD213 are
written to the CPU module after the END
instruction execution in the scan where this
relay is turned on.
M9025
SM211 Clock data error
OFF : No error
ON : Error
This relay turns on if an error occurs in the
clock data (SD210 to SD213), and is off while
there is no error.
S (Request) M9026
SM213
Clock data read
request
OFF : Ignored
ON : Read request
This relay is turned on to read clock data and
store them as BCD values into SD210 to
SD213.

Turns on when an access to CPU No.1 from
another CPU becomes possible after power-
on or reset operation. This relay is used as an
interlock for accessing CPU No.1 when the
multiple CPU synchronous setting is set to
asynchronous.
