750-891 Programmable fieldbus controller

In conjunction with the WAGO-I/O-SYSTEM, the Modbus TCP controller can be used as a programmable controller in ETHERNET networks.

The controller recognizes the plugged I/O modules and creates a local process image from them. This can be a mixed arrangement of analog (data exchange word by word) and digital (data exchange bit by bit) modules.

The two ETHERNET interfaces and the integrated switch enable wiring of the fieldbus in line topology. Additional Infrastructure elements such as switches or hubs can thus be omitted. Both interfaces support Autonegotiation and Auto-MDI(X).

With the DIP switch, the last byte of the IP address and the reference of the IP address can be specified.

The controller is suitable for fieldbus communication in Modbus® networks. In addition, a variety of standardized ETHERNET protocols are supported (HTTP(S), BootP, DHCP, DNS, SNTP, (S)FTP, SNMP).

An integrated web server provides the user with configuration options and status information of the controller. The device is programmable according to IEC 61131-3, supports multitasking and has a buffered real-time clock.
