The GE Fanuc Emerson IC698CPE020 is a high-performance PACSystems RX7i CPU featuring a 700 MHz processor and 20 MB of total memory. Equipped with dual Ethernet ports and VME64 architecture, it delivers rapid control logic execution and robust networking for large-scale industrial applications.
The IC698CPE020 serves as the primary intelligence center for the PACSystems RX7i platform, utilizing a 700 MHz Pentium III microprocessor to deliver rapid execution of complex industrial algorithms. This rack-mounted CPU actively processes user-defined programs and manages high-density I/O configurations with exceptional speed. Specifically, the module handles up to 32K discrete I/O points and 32K words for both analog inputs and outputs. By integrating 10 MB of battery-backed user memory alongside 10 MB of non-volatile flash memory, the IC698CPE020 ensures that critical application data remains secure even during total power loss.
Connectivity remains a core strength of this CPU, as it features dual 10/100 Mbps Ethernet ports directly integrated into the faceplate. These ports actively support a wide variety of industrial protocols, including Ethernet Global Data (EGD), Modbus/TCP, and SRTP. Moreover, the module provides three isolated serial ports that accommodate RS-232 and RS-485 standards. This multi-layered communication architecture allows the processor to synchronize data seamlessly with HMI panels, remote I/O blocks, and third-party Modbus RTU devices. Consequently, facilities can implement the IC698CPE020 as a central gateway within a distributed plant network.
Because it leverages the VME64 backplane standard, the IC698CPE020 facilitates high-speed data throughput across the entire RX7i chassis. This architecture enables the CPU to support intensive mathematical functions, including floating-point calculations and complex Boolean logic. Developers can program the unit using Proficy Machine Edition (version 4.0 or higher), which supports multiple IEC 61131-3 languages such as Ladder Diagram, Structured Text, and C. Furthermore, the built-in web server and FTP functionality allow up to 16 concurrent users to monitor real-time data or perform file transfers, significantly enhancing remote diagnostic capabilities.
The hardware reflects a ruggedized design intended for the most demanding industrial sectors, including power generation and large-scale manufacturing. Despite its high processing power, the module maintains a compact profile (4 x 8 x 29.2 cm), allowing it to fit into standard RX7i rack slots. To maintain long-term reliability, the CPU incorporates advanced data monitoring and time synchronization features. By utilizing a modular programming approach—supporting up to 512 individual program blocks—engineering teams can maintain and update specific logic segments without disrupting the entire automation sequence.
