GE IC698RMX016 RX7i Redundancy Memory Exchange
User RAM MemoryThe RX7i CPUs have 10 Mbytes of battery-backed CMOS
RAM memory for user data (program, configuration, register
data, and symbolic variable) storage.
User Flash Memory
The RX7i CPUs have 10 Mbytes of built-in flash memory for
user data (program, configuration, register data, and
symbolic variable) storage. Use of this flash memory is
optional.
Firmware Storage in Flash Memory
This CPU uses non-volatile flash memory for storing the
operating system firmware. This allows firmware to be
updated without disassembling the module or replacing
EPROMs. The operating system firmware is updated by
connecting a PC compatible computer to the module’s
RS-232 serial port and running the software included with
the firmware upgrade kit.
the CPU, using the Initial IP Address software tool. After
setting the IP address, connect the RX7i and the computer
running the programming software to the Ethernet Interface.
For detailed information on programmer connection via
Ethernet TCP/IP, refer to the TCP/IP Ethernet
Communications for PACSystems RX7i User’s Manual,
GFK-2224.
For a description of programming functions, consult
Proficy™ Machine Edition Logic Developer-PLC Getting
Started, GFK-1918 and the programming software online
help.
Serial Ports
The CPU has three independent, on-board serial ports,
accessed by connectors on the front of the module. Two of
these ports provide serial interfaces to external devices.
Port 1 is also used for firmware upgrades. The third on board serial port is used as the Ethernet station manager
port. All serial ports are isolated.

It is the responsibility of the OEM, system integrator, or end
user to properly install the control system equipment for safe
and reliable operation. Product manuals provide detailed
information about installation, startup, and proper use of the
control system equipment.
Installation should not be attempted without referring to the
PACSystems RX7i Installation Manual, GFK-2223.
1. Read and record the 12-digit hexadecimal MAC
Address from the printed label located inside the battery
compartment.
2. Make sure that rack power is off.
3. Install the CPU module in slot 1 of rack 0 (see Figure 1).
Ensure mounting screws are tightened to completely
secure the CPU in the rack.
4. Connect one or both Ethernet ports to the Ethernet
network.
5. Turn on power. The module should power up. When the
CPU has successfully completed initialization, the OK
LED stays on and the RUN and EN LEDs are off; the
EOK LED stays on. The CPU is now ready to be
programmed.
6. Connect the battery to either of the battery connectors
on the module. (You can connect the battery at any step
in the installation process but it will begin to drain
immediately unless power is applied. To maximize
battery life, install it after power has been turned on).
After the program has been verified, the toggle switch can be
moved to the appropriate operation mode position: RUN EN
(run with outputs enabled), RUN DIS (run with outputs
disabled), or STOP. The LEDs indicate the position of the
toggle switch, status of serial port activity, status of Ethernet
interface including Ethernet OK, LAN, STATus, activity, and
10 or 100Mbps rate used. For details, see “LEDs” on page 6.
Programmer Connection
The programmer can communicate with the CPU via the
embedded or rack-based Ethernet interface, or via serial port
1 or serial port 2.
The programmer uses SNP for serial communications with
the CPU. For information on connecting to a serial port, see
“Serial Cable Lengths and Shielding“ on page 4.
Connecting your programmer via an Ethernet TCP/IP
network requires a CAT5 standard Ethernet cable with RJ-45
connectors. Before connecting the programmer and RX7i to
the Ethernet TCP/IP network you must set the IP address in
