The 750-841 Series upgraded Ethernet TCP/IP Programmable Fieldbus Controller features new functions such as double the data memory to 256kb, the addition of a multi-tasking operating system, and the ability to complete on-line programming changes. Key features of the Ethernet Controller include a 32bit RISC processor; 512kb program memory, 24kb retentive memory, 100Mbits/s Ethernet, IEC-61131-3 programming and the latest open architecture software interfaces and protocols including the industrial Ethernet protocols ModbusTCP and EtherNet/IP. As part of the WAGO-I/O-SYSTEM, the Ethernet Controller is 100% compatible with all 750 series I/O modules allowing the flexibility to interface with over 100 modular (2,4, or 8 channel) digital, analog, and special function I/O modules. Additional features include a real-time clock for time stamping and scheduling applications, as well as having programs stored in flash memory to ensure system integrity on recovery from power failure–eliminating the need for periodic battery replacement.
