GE PACSystems™ RX7i CPE040-AA Central Processing Unit

GE PACSystems™ RX7i CPE040-AA Central Processing Unit

DESCRIPTION

The RX7i CPUs are programmed and configured by the programming software to perform real time  control of machines, processes, and material handling systems. The CPU communicates with I/O and  smart option modules over a rack-mounted backplane using the VME64 Standard format. It  communicates with the programmer and HMI devices via the embedded Ethernet ports or a serial port  using SNP Slave protocol.

Features

■ Contains 64 Mbytes each of battery-backed user memory and non-volatile flash user memory for  user data (program, configuration, register data, and symbolic variable) storage.  

■ Access to bulk memory via reference table %W.  

■ Configurable data and program memory.  

■ Programming in Ladder Diagram, C, Structured Text, and Function Block Diagram.  

■ Auto-located Symbolic Variables that can use any amount of user memory.  

■ Support for Series 90-70 discrete and analog I/O, communications, and other modules. For a list  of modules supported, refer to the PACSystems RX7i Installation Manual, GFK-2223.  

■ Support for all non-GE Fanuc VME modules supported by Series 90-70.  

■ PLC data monitoring over the web. Allows a combined total of up to 16 web server and FTP  connections.  

■ Up to 512 program blocks. Maximum size for a block is 128KB.  

■ Test Edit mode that allows you to easily test modifications to a running program.  

■ Bit-in-word referencing  

■ Battery-backed calendar clock.   CPU and module firmware upgrades via Winloader through CPU’s RS-232 or RS-485 serial port.  

■ Three isolated serial ports: an RS-485 serial port, an RS-232 serial port, and an RS-232 Ethernet  station manager serial port. 

■ An embedded Ethernet interface with:  

− Data exchange using Ethernet Global Data (EGD)  

− TCP/IP communication services using SRTP  

− Modbus TCP server  

− Full PLC programming and configuration services  

− Comprehensive station management and diagnostic tools  

− Two full-duplex 10BaseT/100BaseT/TX (RJ-45 Connector) ports with an internal network  switch providing auto-negotiated network speed, duplex mode, and crossover detection.

Installation in Hazardous Locations

The following information is for products bearing the UL marking for Hazardous Locations:

WARNING - EXPLOSION HAZARD - SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR CLASS  I, DIVISION 2;  

WARNING - EXPLOSION HAZARD - WHEN IN HAZARDOUS LOCATIONS, TURN OFF POWER BEFORE  REPLACING OR WIRING MODULES; AND  

WARNING - EXPLOSION HAZARD - DO NOT CONNECT OR DISCONNECT EQUIPMENT UNLESS POWER HAS  BEEN SWITCHED OFF OR THE AREA IS KNOWN TO BE NONHAZARDOUS.  

EQUIPMENT LABELED WITH REFERENCE TO CLASS I, GROUPS A, B, C, & D, DIV. 2 HAZARDOUS  LOCATIONS IS SUITABLE FOR USE IN CLASS I, DIVISION 2, GROUPS A, B, C, D OR NON-HAZARDOUS  LOCATIONS ONLY.

Configuration of IP Address is  Required Before Using Ethernet  Communications

The Ethernet Interface within the CPU module cannot operate on a network until a  valid IP address is configured. The necessary Ethernet addressing information must  be configured prior to actual network operation, or to recover from inadvertent  changes to the Ethernet addressing data at the Ethernet Interface. Use one of the  following methods to initially assign an IP address:

■Connect a serial terminal to the Station Manager port of the PACSystems  RX7i. Then use the CHSOSW command to enter the desired IP address. For  details, see the PACSystems TCP/IP Communications Station Manager  manual, GFK-2225.  

■ Temporarily assign an IP address to the module using the SetIP tool over the  Ethernet network. For details, see TCP/IP Ethernet Communications for  PACSystems, GFK-2224.  

■ The Ethernet Interface automatically obtains a temporary IP Address from a  BOOTP server on the network. For details, see TCP/IP Ethernet  Communications for PACSystems, GFK-2224.

Once a temporary IP address has been set up, the Ethernet Interface can be  accessed over the network (such as by the Machine Edition programming software).  The programmer should then be used to configure the proper IP address for the  Ethernet Interface.
