Comparison Output Function
The comparison output function outputs ON/OFF signals comparing the count value with any point or range set by the
user.
The coincidence output function or the cam switch function can be selected depending on the processing method.
Set the comparison output function in the parameter setting window or Comparison output setting (address: 0100
