The Real Time Sample (RTS) period is too low.

The following table indicates the minimum RTS value (in milliseconds) that you can enter for the 1756-IF16 and 1756-IF8 modules, based on the Module Filter value.

where:
Single = Single-ended mode
Diff = Differential mode
HS = High-speed mode
For example, for a Module Filter value of 10 Hz on an IF16 module in Integer Single-ended mode, the minimum RTS value is 488 ms.
