(4) This instructions sets the minute selected from 0 to 59 (0 to 59 minutes) with BIN value specified by
(5) This instructions sets the second selected from 0 to 59 (0 to 59 seconds) with BIN value specified by
(6) This instructions specifies the following values at n so that the data to be compared can be specified.
The bit configuration specified at n is as follows.
(a) Clock data to be compared (from 0 to 2nd bit)
• 0: Does not compare specified clock data (hour/minute/second).
• 1: Compares specified clock data (hour/minute/second).
(b) Operation data to be compared (15th bit)
• 0: Compares the clock data specified by
• 1: Compares the clock data specified by
Ignores the clock data specified by

(7) If the data stored in the devices to be compared are not recognized as date data, SM709 will be turned on after the
instruction execution and no-conductive status will be made. Once SM709 is turned on, on-status will be retained till
when the CPU modules are reset or powered off. Therefore, turn off SM709 if necessary.
Moreover, if the range of devices specified by
will be turned on and no-conductive status will be made.
