to the network.

One or more nodes on the
network have an incorrect
baud rate

Correct the baud rates.

Network is shorted or
improperly wired

Check network cable
connections.

Module has same node
address as a 5/01 or fixed
controller (point-to-point
connection)

Reconfigure the module node
address, refer to chapter 3,

Module Setup Procedure

.

The maximum node address
of the previous node is lower
than the module address

Change the maximum node
address of the previous node.

Duplicate Node

LED flashing red

Module has same node
address as a 5/02 or 5/03
(point-to-point connection)

Change the module node
address.

LED flashing red

Module has same node
address as another node
(DH485 network connect ion)

Change the module node
address.

No Response
