Settings are made on the AD-VL 500 .
Since the AD-VL 500 may access external Modbus slaves for data communication, a
higher-level error monitoring of the master-slave data traffic takes place at the RS485

changes to red. Possible errors are e.g.

the slave is not connected or does not respond for another reason.
•
Slave Exception: Reasons can be e.g. an incorrect number of data words or an
incorrect or non-existent register.
