Operation, Protection, and Module Status
User RAM Memory
Operation of this module can be controlled by the threeposition 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 eight
CPU LEDs on the front of the module. (See “LED Operation”
on page 5)
The CPU has 10 Mbytes of battery-backed CMOS RAM
memory for user data (program, configuration, register data,
and symbolic variable) storage.
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.
Specific indication of a low or failed battery is described in
the PACSystems CPU Reference Manual, GFK-2222.
User Flash Memory
The CPU has 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.
Installation
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 RX3i Hardware and Installation Manual,
GFK-2314.
Mode Switch and Battery Compartment
1.
Make sure that rack power is off.
2.
Install the CPU module in rack 0. The CPU requires two
slots and can use any slots except the highest
numbered (rightmost) slot. Ensure mounting screws are
tightened to completely secure the CPU in the rack.
3.
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
CPU is now ready to be programmed.
4.
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 mode switch can be
moved to the appropriate operation mode position: RUN I/O
ENABLED, RUN OUTPUT DISABLE, or STOP. The LEDs
indicate the position of the mode switch and status of serial
port activity. For details, see “LED Operation” on page 5.

Serial Cable Lengths and Shielding
Programmer Connection
The programmer can communicate with the CPU via the
serial port 1, serial port 2, or the rack-based Ethernet
interface.
If you connect your programmer via an Ethernet TCP/IP
network, you will need a CAT5 standard Ethernet cable with
RJ-45 connectors. Before connecting the programmer and
RX3i to the Ethernet TCP/IP network you must set the IP
address, using the Initial IP Address software tool. After
setting the IP address, connect the RX3i 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 User’s Manual,
GFK-2224.
For a description of programming functions, consult
Proficy™ Machine Edition Logic Developer-PLC Getting
Started, GFK-1918 and the software online help.
Serial Ports
The CPU has two independent, on-board serial ports,
accessed by connectors on the front of the module. These
ports provide serial interfaces to external devices.
The connection from a CPU serial port COM1 to the serial
port on a computer or other serial device requires a serial
cable. This connection can be made with the IC200CBL001
cable kit or you can build cables to fit the needs of your
particular application. See the PACSystems CPU Reference
Manual, GFK-2222 for more information on serial
communications, cables, and converters.
Maximum cable lengths (the total length from the CPU to the
last device attached to the serial cable) are:
■ Port 1 (RS-232) – 15 meters (50 ft.), shielded cable
optional
■ Port 2 (RS-485) – 1200 meters (4000 ft.), shielded cable
required
Port 1
Port 1 (COM1) is RS-232 compatible. It has a 9-pin, female,
D-sub connector with a standard pin out. This is a DCE (data
communications equipment) port that allows a simple
straight-through cable to connect with a standard AT-style
RS-232 port.
The COM1 Active LED provides the status of serial port
activity.

The RX3i CPU and I/O system is configured with Machine
Edition PLC-Logic Developer programming software.
The CPU verifies the actual module and rack configuration at
power-up and periodically during operation. The actual
configuration must be the same as the programmed
configuration. Deviations are reported to the CPU alarm
processor function for configured fault response. Refer to the
Proficy Machine Edition Logic Developer-PLC Getting
Started Manual, GFK-1918 and the online help for a
description of configuration functions.
Ethernet Global Data (EGD)
Each RX3i CPU supports up to 255 simultaneous Ethernet
Global Data (EGD) exchanges across all Ethernet interfaces
in the PLC. EGD exchanges must be configured in the
programming software and stored into the CPU. The EGD
configuration can also be loaded from the CPU into the
programming software. Both produced and consumed
exchanges can be configured. RX3i CPUs support using
only part of a consumed EGD exchange, and EGD
exchange production and consumption to the broadcast IP
address of the local subnet.
The RX3i CPU supports 2msec EGD exchange production
and timeout resolution. RX3i EGD exchanges can be
configured for a production period of 0, indicating the
exchange is to be produced every output scan. These “as
fast as possible” exchanges are not produced more often
than 2msec. RX3i CPUs support enhanced EGD freshness,
providing better EGD timeliness than Series 90-30 CPU
products.
During EGD configuration, RX3i Ethernet interfaces are
identified by their Rack/Slot location.
Firmware Upgrades
The CPU receives firmware upgrades through a CPU serial
port. To install a firmware upgrade, connect WinLoader to
the CPU RS-232 or RS-485 serial port. Since you are
connecting directly to the CPU, there is no need to specify
the Rack/Slot location. For upgrades to smart modules (the
IC695ETM001, for example), which are performed indirectly
via the CPU serial port, you must specify a rack/slot location.
