S
1,S2 and S represent time values. Each
specifying the head address of 3 data devices. S is
compared to the time period defined by S1 and S2.
The result is indicated in the 3 bit devices specified
by the head address D.
The bit devices in D indicate the following:
D
+0 is set ON, when the time in S is less than the times in S1 and S2.
D
+1 is set ON, when the time in S is between the times in S1 and S2.
D
+2 is set ON, when the time in S is greater than the times in S1 and S2.
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 range of values for S
1 and S+0 is0to23(Hours).
- The valid range of values for S
2 and S+1 is0to59(Minutes).
- The valid range of values for S
3 and S+2 is0to59(Seconds).
