Set the Input Filter Time
To set the input filter time, set the associated bits in the output image table
(complementary word) for the module.
Read 2 C = Counter Input value of input 15
Write 1 Not used CF CR Input Filter 12...15 Input Filter 0...11
Where
Note:
I = Input
C = Counter value for input 15
CF = Counter fast – where 1 = fast input (raw data), 0 standard input filtered data
CR = Counter reset
C, CR, and CF not available when used with any series 1794-ASB or 1794-ASB2 remote I/O adapter modules.
