Step 3 - Y; Step 4 - Y Limit Control; Conversion Of The Data Format - WAGO I/O-SYSTEM 750 Manual

2.1.1.8.3 Step 3 – Y
In this step, the value Y
converted into the DAC format, leading sign-less 16 bit integer. The context
of the conversion is described below:
2.1.1.8.4 Step 4 – Y
The limit control monitors whether the value Y
desired value range. This value range is defined by the parameter underrange
limit value (UNR) and the overrange limit value (OVR). Via bit 7 of the
register 32, it is also possible to activate a limit of the value Y
During the determination of the calibration values for the manufacturer or user
calibration, no limit should be placed. You can achieve this by configuring the
overrange and underrange limit values to the maximum or minimum value
(65535 or 0) or by writing a 0 to bit 7 of register 32.

Register Name
If you would like to set the limits to defined analog output values, then these
must be determined either like the calibration values in step 5 or calculated
from these.
