7.1.6 Filter Time Constant of the Universal Input 1-8 (40159-40166)
These 16-bit registers contain a time constant low pass filter. The value is expressed in
seconds. Valid values must be between 0 and 60 seconds. The default filter value is 2
seconds. Setting the value to 0 disables the filter.
In case of the UI shortcut or open-loop, the filter is reset and the UI value filtering is
stopped.
7.1.7 Resolution of the Universal Inputs (40167)
This register is used to determine the bit resolution for each of the universal inputs.
Setting the bit to 0 sets the resolution of the converter to 12-bit. Setting the bit to 1 sets
the resolution of the converter to 16-bit.
Each input can be configured separately in accordance with the following table:
