GE IC697CMM711 Serial Communications Coprocessor
August 2004
The RX7i CPUs are programmed and configured by the programming software to perform real time
control of machines, processes, and material handling systems. The CPU communicates with I/O and
smart option modules over a rack-mounted backplane using the VME64 Standard format. It
communicates with the programmer and HMI devices via the embedded Ethernet ports or a serial port
using SNP Slave protocol.

CPE020: 700MHz Pentium III microprocessor
Features
Note: For additional features, refer to the Important Product Information document provided with
each CPU.
■ Contains 10 Mbytes of battery-backed user memory and 10 Mbytes of non-volatile flash user
memory.
■ Provides access to bulk memory via reference table %W. The upper limit of this memory area can
be configured to the maximum available user RAM.
■ Configurable data and program memory.
■ Programming in Ladder Diagram and C.
■ Supports auto-located Symbolic Variables that can use any amount of user memory.
■ Reference table sizes include 32Kbits for discrete %I and %Q and up to 32Kwords each for
analog %AI and %AQ.
■ Supports Series 90-70 discrete and analog I/O, communications, and other modules. For a list of
modules supported, refer to the PACSystems RX7i Installation Manual, GFK-2223.
■ Supports all non-GE Fanuc VME modules supported by Series 90-70.
■ Supports PLC data monitoring over the web. Allows a combined total of up to 16 web server and
FTP connections.
■ Supports up to 512 program blocks. Maximum size for a block is 128KB.
■ Test Edit mode allows you to easily test modifications to a running program.
■ Bit-in-word referencing allows you to specify individual bits in a WORD reference in retentive
memory as inputs and outputs of Boolean expressions, function blocks, and calls that accept bit
parameters.
■ Battery-backed calendar clock.
■ In-system upgradeable firmware.
■ Three isolated serial ports: an RS-485 serial port, an RS-232 serial port, and an RS-232 Ethernet
station manager serial port.
■ The embedded Ethernet interface provides:
− Data exchange using Ethernet Global Data (EGD)
− TCP/IP communication services using SRTP
− Full PLC programming and configuration services
− Comprehensive station management and diagnostic tools
− Two full-duplex 10BaseT/100BaseT/TX (RJ-45 Connector) ports with an internal network
switch providing auto-negotiated network speed, duplex mode, and crossover detection.

Operation, Protection, and Module Status
Operation of this module can be controlled by the three position RUN/STOP switch or remotely by an attached
programmer and programming software. Program and
configuration data can be locked through software
passwords. The status of the CPU is indicated by the three
CPU LEDs on the front of the module. (For details, see
“Indicators.”) Two LEDs indicate activity on the serial ports.
Seven additional LEDs indicate the status of the Ethernet
interface. The RUN/STOP switch can be disabled.
Battery
A three-cell lithium battery pack (IC698ACC701) is installed
as shown in the figure below. The battery maintains program
and data memory when power is removed and operates the
calendar clock. When replacing the battery, be sure to install
a new battery before disconnecting the old one.
Disposal of lithium batteries must be done in
accordance with federal, state, and local regulations. Be
sure to consult with the appropriate regulatory agencies
before disposing of batteries. For details, refer to the
Material Safety Data Sheet provided with the battery.
Specific indication of a low or failed battery is described in
the PACSystems CPU Reference Manual, GFK-2222.
