Controller MODBUS TCP; Generation 4; 2 x ETHERNET (750-891)

The WAGO 750-891 programmable Fieldbus Controller (PFC) combines the functionality of Modbus TCP-based Fieldbus Coupler, as the head station of the node assembly, with the functionality of a Programmable Logic Controller (PLC).

The 750-891 can be used for applications in machine and plant construction as well as in the process industry and building technology.

The two ETHERNET interfaces with the integrated switch enable a line topology to be set up without additional infrastructure elements, such as switches or hubs.

With the DIP switch the last byte of the IP address, as well as the assignment of the IP address (DHCP, BootP, firm setting) can be given.

In the controller, all input signals from the sensors are combined. After connecting the controller, the controller determines which I/O modules are on the node and creates a local process image from these. Analog and specialty module data is sent via words and/or bytes; digital data is grouped bit-by-bit.
