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.
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 Supports OPC UA ▪...
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 RD S D 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...
Real-Time Clock Battery The CPE302 is shipped with a real time Figure 1: Real-Time Clock clock (RTC) battery (IC690ACC001) Battery 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 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.
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.
Green, CPU is in boot mode and is waiting blinking in for a firmware update through a unison with serial port. EN — indicates outputs enabled. Green, ON Output scan is enabled. steady Output scan is disabled. CM — indicates activity on the serial communications port. Green, blinking Signal activity on the COM1 port.
Energy Pack near its end of life and should Red, blinking replaced soon. Energy Pack is charabove its minimum Green, ON operating voltage. steady SYS FLT — indicates presence of a fatal fault. No fatal faults. CPU is in Stop/Faulted mode because a fatal fault Red, ON has occurred.
As the consignee, it is your responsibility to register a claim with the carrier for damage incurred during shipment. Emerson Automation Solutions will fully cooperate with you, however, should such action be necessary. After unpacking the RX3i equipment, record all serial numbers. Serial numbers are required if you should need to contact Customer Care during the warranty period.
RX3i rack systems, refer to the PACSystems RX3i System Manual, GFK-2314. If you need technical help, contact Technical Support. For phone numbers and email addresses, see the back cover of this Guide. Installation in Hazardous Areas The following information is for products bearing the UL marking for...
Module Installation For initial startup and configuration of the CPE302, complete the following steps. For full details on CPE302 operation, refer to the PACSystems RX3i and CPU Reference Manual, GFK-2222. 1. Remove the pull-tab from the Real Time Clock (RTC) battery, located on the back of the CPE302.
The CPU’s S TATUS LED will blink green during this time. Module Initial Startup You Will Need: • PACSystems RX3i CPU Firmware 8.00 or later. • PAC* Machine Edition configuration and programming software, version 8.0 or later. •...
Initial Configuration 1. Using PAC Machine Edition (PME) software, configure the CPE302 in an RX3i target. Note: If you intend to use the module’s embedded Ethernet interface, you will probably need to assign it a new IP address. To configure the embedded Ethernet interface in Machine Edition, expand the CPU slot to display the Ethernet daughterboard.
2. Go online with the target and download the configuration. You can use one of the following methods for the initial connection to the CPE302: a. Using an IC693CBL316 cable, connect to the module’s RJ-25 RS-232 serial port to the programmer computer. The computer must be equipped with an RS-232 serial port with a standard AT-style nine-pin male D-connector.
