4.2.8 Limit switch output function
This function is used to output the ON/OFF signal corresponding to the range of watch
data set for each output device.
It is possible to set the output device for a maximum of 32 points.
(1) The limit switch output function serves to output the ON to the output device while
the value of watch data is located within the ON output area set by (ON Value)
and (OFF Value).
To execute the limit switch output function, it is necessary to set each data using
the peripheral device.
