SM206 PAUSE enable coil
OFF : PAUSE disabled
ON : PAUSE enabled
PAUSE status is entered if this relay is ON when the
PAUSE contact goes ON

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.
U M9025
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.
S (Request) M9026
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
completed
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.

Turned ON when access can be made to the CPU
module No.2 from the other CPU module at power-on
or reset operation. SM221 is used as interlock for
accessing the CPU module No.2 when the multiple
CPU synchronous setting is asynchronous.

Turned ON when access can be made to the CPU
module No.3 from the other CPU module at power-on
or reset operation. SM222 is used as interlock for
accessing the CPU module No.3 when the multiple
CPU synchronous setting is asynchronous.
SM223
CPU No.4 preparation
completed
OFF : CPU No.4 preparation
uncompleted
ON : CPU No.4 preparation
completed
Turned ON when access can be made to the CPU
module No.4 from the other CPU module at power-on
or reset operation. SM223 is used as interlock for
accessing the CPU module No.4 when the multiple
CPU synchronous setting is asynchronous.

Device range check
inhibit flag
OFF : Device range checked
ON : Device range not
checked
• Selects whether to check a device range during
execution of the BMOV, FMOV or DFMOV instruction
(only when the conditions for subset processing are
established).
