The default setting is used to perform AD conversion, converting analog out-
put values that have been scaled to a count of 0 to 6,000 into corresponding
digital values in the output signal range. Scaling can be used to change
scaled values that correspond to the output signal range into other values
required by the user (industry unit values). Scaling also eliminates the need
for ladder programming in the Master to perform math operations. The follow-
ing two methods of scaling can be used.
Default scaling converts analog output values into voltage or current values.
The units used are mV or
formed according to the output range, as shown in the following table.
