Operands:
S
1
: hours of comparison time, range is K0~K23 S
2
: minutes of comparison time, range is K0~K59
S
3
: seconds of comparison time, range is K0~K59 S : Current clock information (occupies 3
continuous addresses) D : Comparison result (occupies 3 continuous addresses)
Description:
1. S

are compared to the current values of the real-time clock S and save the comparison
result in D .
2. S is the hour of the current time and the range is K0~K23. S +1 is the minutes of the current
time and the range is K0~K59. S +2 is the seconds of the current time and the range is
K0~K59.
3. The current time of the RTC specified by S is read by using the TRD instruction previously in
the program and then compared by using TCMP instruction. If the contents of S exceeds the
range, it will result in “operation error”, the instruction will not execute and M1067=ON,
M1068=ON, and the error code 0E1A (HEX) will be in D1067.
