Time Compare
S1 : the “Hour” for comparison
S2 : the “Minute” for comparison
S3 : the “Second” for comparison
S : the registers of the time combination to do the
comparison
D : the compare result; occupying 3 consecutive
points
Compare the setting value (Hours, Minutes and Seconds which are designated by ~ ) to the time
combination (specied by the head ID of 3 consecutive data devices), and the result of the comparison is
stored to .
When X20 = “ON”, the instruction will be performed.

The current time of the real time clock is stored in Special Registers D9013~D9015.
D9015 (Hours), D9014 (Minutes), D9013 (Seconds)
When X20 = “OFF”, the instruction is disabled, the “ON”/“OFF” status of M0, M1 and M2 remains the same as the
status before X20 = “OFF”.
Please use serial or parallel links of M0~M2 to generate the result as “≥”, “≤” or “≠”.
If the content value of the register designated by exceeding the time value required, the PLC will regard that as
an operational error.
