6.1.4 Error
handling
Error
Cause / remedy
No communication with other bus users
The device address is 255, which means
that communication is not active.
Set the device address to a value be-
tween 1 and 252 (automatic search or
manual predefinition).
The subnetwork address (area or line) of
the line couplers and / or the bus users do
not correspond.
Check the subnetwork addresses or
reassign them.
The subnetwork address (SNA) has not
been adopted by the superposed line
coupler
There is no superposed line coupler, or
the line coupler is configured in a way that
it does not send the SNA to the line.
Configure the line coupler accordingly or
predefine the SNA manually.
Fault status message
6001 >1 identical bus address
There are several bus users with identical
device addresses on the network. Correct
the device addresses on the respective
devices accordingly.
6.2 Activating

Communication is activated when:
•
The device has a valid device address

If a line coupler superposed in the network topology delivers SNA information other
than the values set for the area and the line, the line coupler’s values will be adopted
•
If 2 devices have identical device addresses, an error message will be delivered
