An upgraded Ethernet TCP/IP programmable fieldbus controller offers data memory to 256 kbytes, a multitasking operating system, and the ability to complete online programming changes.
Designated the 750-841, the controller features a 32-bit Risc processor, 512-kbytes programming memory, 24-kbytes retentive memory, 100-Mbits/sec Ethernet, IEC-61131-3 programming, and the latest open-architecture software interfaces and protocols. The controller is 100% compatible with all 750 Series I/O modules allowing the flexibility to interface with over 100 modular (two, four, or eight-channel) digital, analog, and special-function I/O modules. The 750-841 has a real-time clock for time-stamping and scheduling applications. To ensure system integrity on recovery from a power failure, programs are stored in flash memory.
