Operands:

S1: Lower bound of the time for comparison (occupies 3 consecutive devices)

S2: 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 S1~ S2 and the comparison result is stored in D.

2.S1, S1 +1, S1 +2: The “hour”, “minute” and “second” of the lower bound value for comparison.

3.S2, S2 +1, S2 +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, S1, S2 exceed the available range, operation error occurs and M1067 = ON, M1068 = ON. D1067 stores the error code 0E1A (HEX).

6.If S < S1 and S < S2, D is ON. When S > S1 and S > S2, D+2 is ON. For other conditions, D + 1 will be ON. (Lower bound S1 should be less than upper bound S2.)

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.
