Functions
Output Point 1
The upper/lower limit function is used to restrict output signals so that conver-
sion data above the upper limit or below the lower limit is made constant. This
function can be set individually for each output point.
Even if data above the upper limit or below the lower limit is set as conversion
data in RAM, the upper or lower limit value will be stored in RAM whichever appli-
cable.
When the scaling function is enabled, set the upper and lower limits in engineer-
ing units. Even if reverse scaling is specified, the lower limit must be smaller than
the upper limit.
To enable the upper/lower limit function, set the upper and lower limits, turn ON
the Upper/Lower Limit Enable Bit, and turn ON the Parameter Update Bit in the
allocated I/O words. Conversion data in RAM will be rewritten and the Analog
Output Unit will generate output signals according to the new parameter set-
tings.
When conversion data exceeds the upper limit, the output signal remains at the
upper limit. Likewise, when conversion data drops below the lower limit, the out-
put signal remains at the lower limit.
