TM251MESE Specific Considerations
The TM251MESE has two different Ethernet networks. Each has its own unique IP and MAC addresses.
The two Ethernet networks are called Ethernet 1 and Ethernet 2:
oEthernet 1 is made of two switched Ethernet ports dedicated to communication between machines or with the control network.
oEthernet 2 is made of one Ethernet port dedicated to the device network and supporting industrial Ethernet connections.
Industrial Ethernet Architecture
This figure presents a typical industrial Ethernet architecture:
A Control network
B Device network
2 Daisy-chained slaves
3 Ethernet switch
4 I/O island (Modbus TCP)
5 Vision sensor (EtherNet/IP)
6 PC and HMI (TCP/UDP)
2, 4, and 5 Industrial Ethernet slave devices (EtherNet/IP / Modbus TCP)
Industrial Ethernet Connections with Modbus TCP IOScanner Architecture
For example, you can:
oConnect your PC to Ethernet 1.
oUse a Modbus TCP IOScanner or EtherNet/IP Scanner with the Ethernet 2.
This figure is an example of an industrial Ethernet architecture with the TM251MESE.
