Introduction to bridging
Bridging Example
At a glance
The following pages present an example of PLC configurations bridging and its transparent PLC adresses.
Bridging Example
The following example consists of the following PLC configurations:
Configuration 3: this Modicon M340 configuration consists of the following communication modules:
An Ethernet-Modbus processor with IP address 139.160.235.34 and Modbus Master. The
processor is in slot 0 of the configuration so that the topological address of this processor’s
Ethernet channel is 0.0.3 and the topological address of this processor’s Modbus channel is
0.0.0.
An Ethernet module BMX NOE 0100 with IP address 118.159.35.2. The Ethernet module is in slot 5 of the configuration so that the topological address of this Ethernet module’s channel is 0.5.0.
Configuration 1: this configuration consists of a remote PLC linked to processor’s Ethernet channel of the configuration 3. The IP address of this remote PLC is 139.160.235.16.
Configuration 2: this configuration consists of a remote PLC linked to Ethernet module’s channel of the configuration 3. The IP address of this remote PLC is 118.159.35.45.
Configuration 4: this configuration consists of a remote PLC linked to processor’s Modbus channel of the configuration 3. The Modbus slave address of this remote PLC is 66.
