AS-i telegram errors on the master
5960
We talk of a telegram error if the expected response telegram from a slave is not received within a
defined time or the signal sequences in the response telegram cannot be interpreted by the AS-i
master.
Examples
:
Due to an electrical fault the AS-i cable is used asymmetrically (one-sided earth fault). The AS-i
signal is no longer clearly recognisable.
The electrical AS-i connection to an AS-i slave is not OK.
The electrical environment of the AS-i system (EMC) interferes with the AS-i telegrams.
Here you cannot see in detail when which error occurred.
