AS-i telegram errors on the master
A telegram error means that the expected response telegram from a slave is not received within a
defined time or that the signal sequences in the response telegram cannot be interpreted by the AS-i
master.
Examples
:
The AS-i line is asymmetrically operated due to an electrical fault (earth fault on one side). In this
case the AS-i signal can no longer be clearly detected.
The electrical AS-i connection to an AS-i slave is not ok.
Interference by the electric environment of the AS-i network (EMC) affects the AS-i telegram
traffic.
Here you cannot see in detail when which fault occurred.
