Setting the Input Delay for Channel Groups
You can only set the input delay for each group of channels. In other words, the
setting for channel 0 applies to inputs 0 to 7 and the setting for channel 8 applies to
inputs 8 to 15.
setting for channel 0 applies to inputs 0 to 7 and the setting for channel 8 applies to
inputs 8 to 15.
Note
The parameters that are entered for the remaining channels (1 to 7 and 9 to 15)
must be equal to the value 0 or 8, otherwise those channels will be reported as
being incorrectly parameterized.

Any hardware interrupts that have occurred in the meantime will be reported after
acknowledgement.

Optimum Signal Propagation Delays
You can achieve the fastest signal propagation delay with the following settings:
•
Both channel groups are parameterized with an input delay of 0.5 ms
•
The Diagnostics parameter is disabled
•
The Diagnostic Interrupt parameter is disabled
