Operands:
S
1
: Lower bound of the time for comparison (occupies 3 consecutive devices) S
2
: Upper bound of
the time for comparison (occupies 3 consecutive devices) S: Current time of RTC (occupies 3
consecutive devices) D: Comparison result (occupies 3 consecutive devices)
Explanations:
1. TZCP instruction compares current RTC time in S with the range set in S
1
~ S
2
and the
comparison result is stored in D.
2. S
1
, S
1
+1, S
1
+2: The “hour”, “minute” and “second” of the lower bound value for comparison.
3. S
2
, S
2
+1, S
2
+2: The “hour”, “minute” and “second” of the upper bound value for comparison.
4. S, S +1, S +2: The “hour”, “minute” and “second” of the current time of RTC.
5. Usually the time of RTC in S is read by TRD instruction first then compared by TZMP
instruction. If operand S, S
1
, S
2
exceed the available range, operation error occurs and
M1067 = ON, M1068 = ON. D1067 stores the error code 0E1A (HEX).
6. If S < S
1
and S < S
2
, D is ON. When S > S
1
and S > S
2
, D+2 is ON. For other conditions, D + 1
will be ON. (Lower bound S
1
should be less than upper bound S
2
.)
Program Example:
When X0 = ON, TZCP instruction executes and M10~M12 will be ON to indicate the comparison
results. When X0 = OFF, the instruction is disabled but the ON/OFF status of M10~M12 remains.
