The Modbus TCP/UDP Fieldbus Coupler connects ETHERNET to the modular WAGO-I/O-SYSTEM.
The fieldbus coupler detects all connected I/O modules and creates a local process image.
Two ETHERNET interfaces and an integrated switch allow the fieldbus to be wired in a line topology. This eliminates additional network devices, such as switches or hubs.
Both interfaces support autonegotiation and Auto-MDI(X).
The rotary switch configures the last byte of the IP address and may be used for IP address assignment (DHCP, BootP).

The coupler is designed for fieldbus communication in MODBUS® networks. It also supports a wide variety of standard ETHERNET protocols (HTTP(S), BootP, DHCP, DNS, SNMP, (S)FTP). An integrated Webserver provides user configuration options, while displaying coupler’s status information.

The device is ideal for operation in harsh environments thanks to:
  • Extended temperature range
  • Greater immunity to impulse voltages and electromagnetic interference
  • Higher vibration and shock resistance
