represent hours, minutes and
seconds respectivel

. This time is compared to the
time value in the 3 data devices specified b
y
the
head address S. The result is indicated in the 3 bit
devices specified b
y
the head address D.
The bit devices in D indicate the followin
g
:
D
+0
is set ON, when the time in S is less than the time in S
1
, S
2
and S
3
.
D
+1
is set ON, when the time in S is equal to the time in S
1
, S
2
and S
3
.
D
+2
is set ON, when the time in S is
g
reater than the time in S
1
, S
2
and S
3
.
Points to note:
a) The status of the destination devices is kept, even if the TCMP instruction is deactivated.
b) The comparison is based on the time value specified in the source devices.
- The valid ran

1
and S
+0
is 0 to 23 (Hours).
- The valid ran

is 0 to 59 (Minutes).
- The valid ran
