SM210 Clock data set request
OFF : Ignored
ON : Set request
• When this relay goes from OFF to ON and after END
instruction execution of subsequent scan, clock data
stored in SD210 to SD213 are written to the CPU
module.
UM9025
SM211 Clock data error
OFF : No error
ON : Error
• ON when error is generated in clock data (SD210 to
SD213) value, and OFF if no error is detected.

SM213
Clock data read
request
OFF : Ignored
ON : Read request
• When this relay is ON, clock data is read to SD210 to
SD213 as BCD values.

completed
OFF : CPU No.1 preparation
uncompleted
ON : CPU No.1 preparation

Turned ON when access can be made to the CPU
module No.1 from the other CPU module at power-on
or reset operation. SM220 is used as interlock for
accessing the CPU module No.1 when the multiple
CPU synchronous setting is asynchronous.
