COUNTER FUNCTION
12.5

Coincidence Detection Function

This function compares "
outputs signals when the values coincide.
The coincidence detection can be set for each channel in units of one points.
(1) Operation of coincidence detection
Md.3
To use the coincidence detection function, set "
to "1: Coincidence detection requested".
Count enable command
The coincidence detection function
starts when the count enable
command is turned ON.

The coincidence detection starts using the value of "
detection point setting" when the count enable command (Y1C to Y1E) is
turned ON.

setting", the count value small (X16, X1A, and X1E) turns OFF and the count
value coincidence (X15, X19, and X1D) turns ON.
The coincidence signal reset command (Y14 to Y16) is turned ON and the
count value coincidence (X15, X19, and X1D) is reset. If the count value

coincidence (X15, X19, and X1D) remains ON, the next coincidence signal
cannot be output.
