Setting Input Filter Times
You can select the input filter time (FT) for channels 00 thru 11 and
channels 12 thru 15. Select the input filter time by setting the
corresponding bits in the output image table (complementary word)
for the module.
For example, to set a filter time of 4ms for an input module at address
rack 1, module group 0, set bits 05, 04, 03, 02, 01, and 00 as shown
below.
