Setting the Input Filter Time
You can select the input filter time (FT) for each group of channels (channels 00
through 11, or channels 12 through 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 a dc input module at address
rack 1, module group 0, set bits 05, 04, 03, 02, 01, and 00 as shown
below.
