Activating analog filters
If you want to use anti-aliasing filters, these are set up as configuration output and con-
figured as Off-task connector (OTC) or function block.
First, drag the output signals defined in the I/O configurator to the margin of the program-
ming surface, in this example “X2_EnableFilter_Ch00” for the analog input 0.

Create a new Off-task connector in the programming window, assign a meaningful name
to the connector, e.g. “low pass filter” and choose “Input” and Data type “BOOL” under
the Connector type option.
