Description
 S
1
: the lower bound setting value for time comparison
S
2
: the upper bound setting value for time comparison
S: current time of RTC
D: comparison result
 Compare the current time of RTC that S designates with S1–S2, the comparison result is stored
in D.
 S
1
, S
1
+ 1, S
1
+ 2: the hour, minute, second of the lower bound setting value for comparison.
 S
2
, S
2
+ 1, S
2
+ 2: the hour, minute, second of the upper bound setting value for comparison.
 S, S + 1, S + 2: the hour, minute, second of the current time of RTC.
 D0 that S designates is usually read the current time of RTC by using TRD instruction and then
doing comparison by TZCP instruction. If S
1
, S
2
and S value exceed the available range, it’s
operation error so the instruction is not executed, M1068 = ON.
 If S < S
1
and S < S
2
, then D = ON; if S > S
1
and S < S
2
, then D+2 = ON. For other conditions
are D+1 = ON
Example
 When X10 = ON, TZCP instruction is executed, and one of M10, M11, and Y2 will be ON. When
X10 = OFF, TZCP instruction is not executed, and M10, M11, and M12 remain their statuses
before X10 = OFF.
