<strong>FLEX</strong> I/O <strong>and</strong> <strong>FLEX</strong> <strong>Integra</strong> Product Data 120V ac 16 Input Module Cat. No. 1794-IA16 37Increasing the Input Filter TimeYou can increase the input filter time (FT) for channels 00 through 11<strong>and</strong>/or channels 12 through 15. Select the input filter time by settingthe corresponding bits in the output image table (complementaryword) for the module.For example, to increase the off-to-on filter time for inputs 0 through11 to 10ms for an ac input module at address rack 1, module group 0,set bits 02, 01, <strong>and</strong> 00 as shown below.15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 0017 16 15 14 13 12 11 10 07 06 05 04 03 02 01 000 0 0 0 1 1O:010FT = 12-15Write Filter Time on system startup.FLLI:00000Input Filter TimesFill FileSource 3Destination #O:010Length 1Dec.
