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.

▪Supports PME’s new GUI management interface for OPC UA configuration

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

2 PACSystems™ RX3i Central Processing Unit IC695CPE302 GFK-3038C

▪Enabled with an embedded Ethernet interface to support up to 32

simultaneous SRTP Server connections, up to 16 simultaneous Modbus/TCP

Server connections, and up to 16 simultaneous communications channels of

either SRTP Channels or Modbus/TCP Client channels. For details, refer to the

PACSystems RX3i TCP/IP Ethernet Communications User Manual, GFK-2224

Information Details.

▪Ability to transfer applications to and from USB 2.0 A type removable data

storage devices, or RDSDs.

▪Compliant with EU RoHS Directive 2002/95/EC using the following

exemptions identified in the Annex: 7(a), 7(c)-I and III, and 15.

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.

5 PACSystems™ RX3i Central Processing Unit IC695CPE302 GFK-3038C

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.
