Operands:

: “Hour” for comparison (K0~K23) S

: “Minute” for comparison (K0~K59) S

: “Second” for

comparison (K0~K59) S: Current time of RTC (occupies 3 consecutive devices) D:

Comparison result (occupies 3 consecutive devices)

Explanations:

1. TCMP instruction compares the time set in S

, S

with RTC current value in S and stores

the comparison result in D.

2. S: “Hour” of current time of RTC. Content: K0~K23. S +1: “Minute” of current time of RTC.

Content: K0~K59. S +2: “Second” of current time of RTC. Content: K0~K59.

3. Usually the time of RTC in S is read by TRD instruction first then compared by TCMP

instruction. If operand S exceeds the available range, operation error occurs and M1067 = ON,

M1068 = ON. D1067 stores the error code 0E1A (HEX).

Program Example:

1. When X0 = ON, the instruction executes and the RTC current time in D20~D22 is compared

with the set value 12:20:45. Comparison result is indicated by M10~M12. When X0 goes from

ON→OFF, the instruction is disabled however the ON/OFF status of M10~M12 remains.

2. Connect M10 ~ M12 in series or in parallel to obtain the results of ≧, ≦, and ≠.
