The Ethernet-based PLC and I/O couplers are designed for use in extreme environments. These modules, part of the 750 XTR series, have two switched Ethernet ports for feedthrough cabling and support any of the XTR digital, analog and specialty I/O modules. The PLC (750-890/040-000) can be programmed with Wago-I/O-Pro-based CoDeSys v.2 software and supports Modbus TCP/UDP fieldbus communications. It provides faster processing speeds and more memory than previous generations. The distributed I/O couplers (750-362/040-000 and 750-363/040-000) offer dedicated fieldbus ports with faster boot-up times. The 750-362/040-000 supports Modbus TCP/UDP while the 750-363/040-000 supports EtherNet/IP communications.
