Item no. 750-352

Fieldbus Coupler ETHERNET; 3rd Generation

This item has been discontinued.
For this item, a successor is available: Modbus TCP 750-362; EtherNet/IPTM 750-363

The 750-352 ETHERNET 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. This process image may include a mixed arrangement of analog (word-by-word data transfer) and digital (bit-by-bit data transfer) modules.

Two ETHERNET interfaces and an integrated switch allow the fieldbus to be wired in a line topology, eliminating the need for additional network devices, such as switches or hubs. Both interfaces support autonegotiation and Auto-MDI(X).

The DIP switch configures the last byte of the IP address and may be used for IP address assignment (DHCP, BootP, static).

The coupler is designed for fieldbus communication in both EtherNet/IP and MODBUS networks. It also supports a wide variety of standard ETHERNET protocols (e.g., HTTP, BootP, DHCP, DNS, SNMP, FTP). An integrated Webserver provides user configuration options, while displaying the coupler's status information.

The system supply is provided directly by the coupler. The field supply is provided via a separate supply module.
