Filter Register (R37) IP/IE3312

The filter time of the A/D converter can be modified in the filter register. Write protection must first be cancelled in the code-word register before it is possible to write into this register. The conversion time of the A/D converter also changes when the filter time is changed. The two values depend directly upon one another. The filter settings always apply to all the channels, and are set in the first register for channel 1. The settings are not effective until after a power restart (switch the Fieldbus Box off and on again).
