48V dc 16 Sink Input Module Cat. No. 1794-IC16 87
Setting Input Filter Times
This module has a built-in 1ms filter. You can select additional input
filter time (FT) for each group of channels (channels 00 through 11, or
channels 12 through 15). Select the additional input filter time by
setting the corresponding bits in the output image table
(complementary word) for the module.
For example, to set an additional filter 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. This would result in a total filter time of 5ms.
