Operands:
S
1
: Lower limit time data S
2
: Upper limit time data S : Current time of the RTC
D : Comparison result (occupies 3 continuous addresses)
Operands S
1
, S
2
, S occupy 3 continuous addresses S
1
should be less than S
2
Description:
1. S is compared to the time of S
1
~ S
2
and the comparison result is stored in D .
2. S
1
, S
1
+1, S
1
+2: represents “Hour”, “Minute”, “Second” of the lower limit time data.
3. S
2
, S
2
+1, S
2
+2: represents “Hour”, “Minute”, “Second” of the Upper limit time data
。
4. S , S +1, S +2: represents “Hour”, “Minute”, “Second” of the current time of calendar.
5. The current time of the calendar specified by S is read by using the TRD instruction previously
in the program and then compared by using TZCP instruction. If the content of S , S
1
, S
2
exceeds the range, it will result in “operation error”. At this time, the instruction will not be
executed and M1067=ON, M1068=ON, and error code 0E1A (HEX) will be written to D1067.
6. If S < S
1
and S < S
2
, D is ON. If S > S
1
and S > S
2
, D +2 is ON. Except for these two situations,
D +1 is ON. (Lower limit S
1
should be less than upper limit S
2
.)
