(b) Comparison of current time data
• This instruction treats the clock data specified by
normally open contact, and compares the data in accordance with the value of n.
• This instruction treats the clock data specified by
data.

When either
given or current time data with specified clock data, the operation error (error
code: 4101) or a malfunction may occurs.
• The range of the devices to be used for the index modification is specified over
the range of the device specified by
• File registers are specified by
(2) This instructions set BIN values for each item.
(3) This instructions sets the time selected from 0 to 23 (midnight to 23 o'clock) with the BIN
value specified by
S1
(4) This instructions sets the minute selected from 0 to 59 (0 to 59 minutes) with BIN value
specified by +1 or
S1
(5) This instructions sets the second selected from 0 to 59 (0 to 59 seconds) with BIN value
specified by +2 or
S1
(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.
This instruction specifies 0 at bits from 3rd to 14th.
The instruction will be non-conductive status without
specifying 0 regardless of the operation result.

If this instruction specifies 1 (on) at 15th bit, the
instruction compares S1 with the current date in
accordance with the bit condition specified at 0 to 2nd
bit.
(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
