GE IC698CPE010 PACSystems™ RX7i Central Processing Unit

GE IC698CPE010 PACSystems™ RX7i 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 10 Mbytes of battery-backed user memory and 10 Mbytes of non-volatile flash user  memory.  

■ Provides access to bulk memory via reference table %W. The upper limit of this memory area can  be configured to the maximum available user RAM.  

■ Configurable data and program memory.  

■ Programming in Ladder Diagram and C.  

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

■ Reference table sizes include 32Kbits for discrete %I and %Q and up to 32Kwords each for  analog %AI and %AQ.  

■ Supports 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.  

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

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

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

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

■ Bit-in-word referencing allows you to specify individual bits in a WORD reference in retentive  memory as inputs and outputs of Boolean expressions, function blocks, and calls that accept bit  parameters.  

■ Battery-backed calendar clock.  

■ In-system upgradeable firmware.  

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

■ The embedded Ethernet interface provides:  

− Data exchange using Ethernet Global Data (EGD)  

− TCP/IP communication services using SRTP  

− 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.

Operation, Protection, and Module Status  

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 three  CPU LEDs on the front of the module. (For details, see  “Indicators.”) Two LEDs indicate activity on the serial ports.  Seven additional LEDs indicate the status of the Ethernet  interface. The RUN/STOP switch can be disabled.

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.

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 RX7i Installation Manual, GFK-2223.

1. Read and record the 12-digit hexadecimal MAC  Address from the printed label located inside the battery  compartment.  

2. Make sure that rack power is off.  

3. Install the CPU module in slot 1 of rack 0.  Ensure mounting screws are tightened to completely  secure the CPU in the rack.  

4. Connect one or both Ethernet ports to the Ethernet  network.  

5. 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  EOK LED stays on. The CPU is now ready to be  programmed.  

6. 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).
