„Shifted Inputs“ mode
In the “Shifted Inputs” mode, the first 16 inputs are alternately set in the transfer protocol in Byte 0 and
Byte 1. With the next 16 inputs, the same takes place for Byte 2 and Byte 3.
„Halved Inputs“ mode
In the “Halved Inputs” mode, every second input is missed out. Only inputs 1, 3, 5, ... are transferred; as
a result, only 2 Bytes are needed for 32 physically-present inputs.

Input filter: DIP switch 11
With the input filter, interference which could affect the input modules is suppressed.
Input filter inactive DIP 11 OFF
Input filter active DIP 11 ON

ATTENTION!
With the filter active, only signals with a duration of
≥
2 ms will be recognised. In order to
comply with the guidelines of the EMC Act, the input filter must be activated.
