Setting Input Filter Time
(Standard Addressing Mode Only)
(not available when used with the 1794-ASB adapter)
You can select the input filter time (FT) for channels 00 and 01. Select
the input filter time by setting the corresponding bits in the
configuration word (word 3) 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 02, 01, and 00 as shown below.
