11-4-2 Analog Output Unit Functions
Scaling
In default setting, the output values are scaled to a count between 0 to 6,000
and converted to analog values in the output signal range. The scaling func-
tion allows user-specified scaling (or industry-specific units) for output signal
ranges. The function eliminates the need for ladder programming in the Mas-
ter Unit to perform math operations. The following two methods of scaling can
be used.
Default Scaling Default scaling converts analog output values into voltage or current values.
The units used are mV or
µ
A. When default scaling is selected, scaling is per-
formed according to the output range, as shown in the following table.
