Faulty AS-i messages on the master
A message error means that the expected response message from a slave is not
received within a defined time or that the signal sequences in the response mes-
sage of the AS-i master cannot be interpreted.
Examples:
•
The AS-i line is asymmetrically operated due to an electric fault (earth fault on
one side). The AS-i signal is no longer clearly recognisable.
•
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 message traffic.
Here you can not see in detail when every individual fault occurred.
