(Note 1) If interrupt occurs many times in one scan, the execution of intterupt program has priority, and the scan time
will be longer.
(Note 2) If more than one interrupt activation request is made from the unit, the process will be carried out from the
smallest slot number or the smallest interrupt program number.

Max. 16 data/ch (Comparison data 0 to Comparison data 15)
Max. 16 points/ch (Comparison match 0 flag to Comparison match F flag)
Read as input relays (X) by user programs.
Multiple comparison match flags can be set for one comparison data.
Depending on the count direction, sets or resets the output when the count value
reaches the target value.
Turns on/off the output when the count value reaches the area of the target value.
2 points/ch
Comparison match 0 flag and comparison match 1 flag can be allocated to
external outputs.
When using the band comparison function, the ON timing characteristics of
external output relays can be changed.
ON timing delay
ON hold time
ON timing delay and ON hold time
Outpus can be forcibly set or reset by the monitor function of programming tool.
Stores the count value when the control signal turns on in the capture register.
Either one of the following functions is usable.
Capture function
Sampling capture function
Activates corresponding interrupt programs when the comparison match 0 flag
and comparison match 1 flag of each channel turns on. (Note 1) (Note 2)
Per 1 channel of high-speed
counter unit
Per 1 high-speed counter unit
Per 1 CPU unit
The count value overwrites the initial value when the power turns on.
Input time constant (noise filter) can be set to reduce noises of input signal lines.
Input A signal, input B signal
(The same time constant for
the both signals)
Input Z signal
Control signal

in the capture register.
