The GE Fanuc IC698CPE020 CPU is a central processing unit for the Rx7i PACsystem RX7i series. The IC698CPE020 CPU belongs to the Rx7i family of performance controllers that are designed to provide application flexibility across multiple hardware platforms. A fully programmed and configured IC698CPE020 CPU can perform real-time control of applications and machine processes and communicate with multiple I/O devices over the Rx7i backplane. The IC698CPE020 CPU is built with the VME64 architecture that supports a wide range of VME embedded technologies with fast data throughput, and it can communicate with a host of Human-Machine Interface devices (HMIs) via embedded Ethernet ports. The IC698CPE020 CPU comes with a 700-Megahertz “Pentium III microprocessor” and a 10-Megabyte RAM and a 10-Megabyte non-volatile flash memory for the storage of user data and programs. The IC698CPE020 CPU can perform both floating points math and Boolean functions and it supports the programming of the users' applications by using the Ladder Diagram, C, Function Block Diagram, and Structured Text programming languages.

The GE Fanuc IC698CPE020 CPU supports up to 512 KB of program blocks and it has a reference data table consisting of 32 Kilobits of %I and %Q discrete data and up to 32 kilowords of %AI and %AQ analog data. The IC698CPE020 CPU is located in Slot 1 of the Rx7i I/O rack and it has a maximum backplane current draw rating of 3.2 Amps at 5 Volts DC voltage. It has 3 rear serial ports that are the RS-485 port, the RS-232 port, and the RS-232 manager port, and a dual embedded Ethernet port that support high-speed TCP/IP communication. The IC698CPE020 CPU also supports the Modbus RTU Slave, SNP, and the Serial I/O communication protocols. The IC698CPE020 CPU is configured by using the Proficy Machine Edition Logic Developer PLC software that is version 4.0 or later.
