1 PACSystems™ RX3i Central Processing Unit IC695CPE302 GFK-3038C
User Features
The PACSystems™RX3i CPE302 can be used to perform real time control of
machines, processes, and material handling systems. The CPU
communicates with the programmer via the internal Ethernet port or a
serial port. It communicates with I/O and Intelligent Option modules over a
dual PCI/Serial backplane.

integration (start, stop, restart, clear, and provisioning mode)
▪Supports the new PAC Security tool available for certificate trust management
of clients and servers
▪Contains 5 Mbytes of user memory and 5 Mbytes of non-volatile flash user
memory
▪Supports Battery-less retention of user memory
▪Configured with an Energy Pack IC695ACC400 to power the CPU long enough
to write user memory to non-volatile storage (NVS) on system power loss
▪Equipped with configurable data and program memory
▪Supports programming in Ladder Diagram, Structured Text, Function Block
Diagram, and C
▪Supports auto-located Symbolic Variables that can use any amount of user
memory
▪Equipped with reference table sizes to include 32 Kbits for discrete %I and %Q
and up to 32Kwords each for analog %AI and %AQ

Switches
The RDSD and Run Mode switches are located behind the front protective
door. The Reset switch is not used. Switch operation is given in the
following table.
Switch Operation
RDSD Switches
Function
Start pushbutton
Pressing this switch initiates RDSD data transfer. (The
three-position switch must be set to Upload or
Download.)
Three-position switch
Enables/disables RDSD data transfer and selects the
direction of data transfer.
Upload
Loads application from CPU to RDSD.
Off
Disables RDSD data transfer.
Download
Stores application from RDSD to CPU.
Run Mode Switch
A three-position switch which operates as follows:
Switch Position
CPU and Sweep Mode
Memory Protection
Run I/O Enable
The CPU runs with I/O sweep
enabled.
User program memory is
read only.
Run Output Disable
The CPU runs with outputs
disabled.
User program memory is
read only.
Stop
The CPU is not allowed to go
into Run mode.
User program memory
can be written.
The Run Mode switch can be disabled in the programming software in Hardware
Configuration (HWC). The switch’s memory protection function can be disabled
separately in HWC. The Run Mode switch is enabled by default. The memory
protection functionality is disabled by default.

Real-Time Clock Battery
The CPE302 is shipped with a real time
clock (RTC) battery (IC690ACC001)
installed, with a pull-tab on the battery.
The pull tab should be removed before
installing the CPE302.
There are no diagnostics or indicators to
monitor RTC battery status. The RTC
battery has an estimated life of 5 years
and must be replaced every 5 years on a
regular maintenance schedule. If the RTC
battery fails, the CPU date and time is
reset to 12:00 AM, 01-10-2000 at startup.
The CPU operates normally with a failed
or missing RTC battery; only the initial
CPU Time-of-day (TOD) clock information
will be incorrect.

Battery
Ethernet Port
The embedded Ethernet interface supports communications with the
Machine Edition programming software using the proprietary SRTP
protocol. The CPE302 CPU provides two SRTP server connections.
The embedded Ethernet interface has one RJ-45 Ethernet port that
automatically senses the data rate (10 Mbps or 100 Mbps), duplex status
(half or full duplex), and cabling arrangement (straight through or
crossover) of the attached link.

Serial Port
The CPE302 provides one RS-232 serial interface to external devices. This
port can be used for firmware upgrades. The port is electrically isolated. For
serial port pin assignments and details on serial communications, refer to
the PACSystems RX3i CPU Reference Manual, GFK-2222.
The RS-232 port does not supply the 5 VDC power offered by other RX3i
and Series 90-30 CPUs. Cable IC693CBL316 must be used for RS-232 serial
connections to the CPE302.
Removable Data Storage Devices
(RDSDs)
The CPE302 provides the ability to transfer applications to and from an
RDSD (USB compatible device, such as a memory stick, smart phone, digital
camera or MP3 device). Once the data is copied to the RDSD, it can be
written to other RX3i CPE302 CPUs with no programmer software needed.
The RDSD interface requires a user-supplied flash memory device that
complies with the USB 2.0 Specification.
The USB port must be enabled in the RX3i configuration in order to transfer
data between the CPU and the RDSD. The CPE302 is shipped with the RDSD
(USB) port enabled. Complete details of the use of RDSDs are found in the
PACSystems RX3i CPU Reference Manual, GFK-2222.

Energy Pack
The CPE302 preserves user memory using an Energy Pack without the need
to periodically replace batteries. The IC695ACC400 Energy Pack powers the
CPU long enough for the CPU to write its user memory contents to the
CPU’s non-volatile storage during a system power loss. Installation of the
Energy Pack is found below.
