Description

IC697CPX928 single slot PLC CPU IC697CPX935

Product description

The CPX 928 is a single slot PLC CPU that is programmed and configured by MS-DOS or Windows based programming software to perform real time control of machines, processes and material handling systems. It communicates with I/O and smart option modules over the rack-mounted backplane using the VME C.1 Standard format.
Supported option modules include LAN Interface modules, Programmable Coprocessor, Alphanumeric Display Coprocessor, Bus Controller for IC660/661 I/O products, Communications modules, I/O Link Interface, and all of the IC697 family of discrete and analog I/O modules.

User RAM Memory
The CPX928 has a built-in memory board with 6 Mbytes of battery-backed CMOS RAM memory for user data (program, configuration, and register data) storage.
User Flash Memory
The CPX928 has 256K of built-in, non-volatile flash memory for user data (program, configuraton, and register data) storage. Use of this flash memory is optional.
Firmware Storage in Flash Memory
This CPU uses flash memory for storing the operating system firmware. This allows firmware to be updated without disassembling the module or replacing EPROMs. The operating system firmware is updated by connecting a PC compatible computer to the module’s serial port and running the software included with the firmware upgrade kit.
Operation, Protection, and Module Status
Operation of this module can be controlled by the three-position RUN/STOP switch or remotely by an attached programmer and programming software.
Program and configuration data can be locked through software passwords or manually by the memory protect keyswitch. When the key is in the protected position, program and configuration data can only be changed by a programmer connected parallel only (to the Bus Transmitter module). The status of a CPU is indicated by the seven green LEDs on the front of the module.

Application field

Operating Temperature
The CPX 928 requires forced air cooling for proper operation in ambient temperatures greater than 50C (122F). A fan capable of 70 CFM (including filters) should be located beneath slot 1 of the rack containing the CPU.
Fan assemblies (IC697ACC 721, IC697ACC724, and IC697ACC744) can be ordered for direct mounting on the IC697 rack. Refer to the applicable Programmable Controller Installation Manual for detailed information.
Installation
It is the responsibility of the OEM, system integrator, or end user to properly install the PLC equipment for safe and reliable operation. Product manuals provide detailed information about installation, startup, and proper use of the PLC equipment. The installation manual, shipped with your PLC programming software, describes how to properly install the equipment.
If the PLC installation must comply with supported standards, such as FCC or CE Directives, please refer to the Installation Requirements for Conformance to Standards, shipped with the PLC programming software, for additional guidelines.
