DAISY-CHAIN ETHERNET CONNECTION
CAUTION
IT IS NOT ALLOWED TO CREATE LOOPS WITH ETHERNET CABLES
Using the daisy-chain connection it is not necessary to use switches to connect the devices.
The following examples show the correct connections.
There must be no loops in the Ethernet cabling, otherwise the communication will not work. The modules and switches
must be connected eliminating any loops. The following examples show the incorrect connections.
The LAN fault-bypass function allows you to keep the connection between the two Ethernet ports of the device ON, in the
event of a power failure. If a device turns off, the chain is not interrupted and the devices downstream of the switched-off
one will still be accessible. This function has a limited duration: the connection remains active for a few days, typically 4.
The fault-bypass function requires that the sum of the lengths of the two cables connected to the switched off module is less
than 100m.

ETHERNET CONNECTION RULES
For the Ethernet cabling between the devices, the use of the unshielded CAT5 or CAT5e cable is required.
FACTORY IP ADDRESS
The default module IP address is static: 192. 168. 90. 101
WEB SERVER
To access the maintenance Web Server with the 192.168.90.101 factory IP address
(Default user: admin; Default password: admin) http://192.168.90.101
CAUTION
DO NOT USE DEVICES WITH THE SAME IP ADDRESS IN THE SAME ETHERNET NETWORK.
