8.24 Clock Instruction
Processing details
• These instructions compare the time data in the devices specified by (s1) and (s2), or compare the time data in the device
specified by (s1) with the current time. Set the comparison target by (s3).
• Set each data in binary.
• Set the "hour" data as in the 24-hour clock in the devices specified by (s1) and (s2) within the range 0 to 23.
• Set the "minute" data in the devices specified by (s1)+1 and (s2)+1 within the range 0 to 59.
• Set the "second" data in the devices specified by (s1)+2 and (s2)+2 within the range 0 to 59.
• Set the following in (s3) as comparison target setting values. The following shows the bit configuration of (s3).
• When 0 is set to the 0 to 2 bits, the time data (hour, minute, and second) are not compared. When 1 is set, the entire time
data (hour, minute, and second) are compared.
• When 0 is set to the 15 bit, the data in the device specified by (s1) and the time data in the device specified by (s2) are
compared. When 1 is set, the data in the device specified by (s1) is compared with the current time. The time data in the
device specified by (s2) is ignored.
• The following table lists processing details of each bit.
• Comparing two specified time data
These instructions compare the time data in the device specified by (s1) with the time data in the device specified by (s2) in accordance with the
conditions set by (s3). (Devices are used as a normally open contact.)
• Comparing specified time data with current time data
These instructions compare the time data in the device specified by (s1) with the current time data in accordance with the conditions set by (s3).
(Devices are used as a normally open contact.) The time data in the device specified by (s2) is regarded as dummy data and ignored.
(1) Set "second" as comparison target.
(2) Set "minute" as comparison target.
(3) Set "hour" as comparison target.
(4) Set 0. If a value other than 0 is set, the operation result will be non-
continuity.
(5) When 1 is set to the 15 bit, the data in the device specified by (s1)
is compared with the current time in accordance with the conditions
set in the 0 to 2 bits.
