 S
1
: Sets the hours of the comparison time, setting range is "K0–K23."
S
2
: Sets the
minutes of the comparison time, setting range is "K0–K59."
S
3
: Sets the seconds of
the comparison time, setting range is "K0–K59."
S
: current calendar time.
D
:
Results of comparison.

Compares the time in hours, minutes, and seconds set in
S
1
–
S
3
with the current
calendar time in hours, minutes, and seconds, with the results of comparison
expressed in
D
.
 S
The hour content of the current calendar time is "K0–K23."
S
+1 comprises the
minutes of the current calendar time, and consists of "K0–K59."
S
+2 comprises
the seconds of the current calendar time, and consists of "K0–K59."

The current calendar time designated by
S
is usually compared using the TCMP
command after using the TRD command to read the current calendar time. If the
content value of
S
exceeds the range, this is considered an operating error, the
command will not execute, and M1068=On.

When X10=On, the command will execute, and the current calendar time in
D20–D22 will be compared with the preset value of 12:20:45; the results will be
displayed in M10–M12. When X10 On→Off, the command will not be executed, but
the On/Off status prior to M10–M12 will be maintained.

If results in the form of ≥, ≤, or ≠ are needed, they can be obtained by series and
parallel connection of M10–M12.
