IC697CPU731 Central Processing Unit

The IC697CPU731  is a single-slot PLC CPU that resides in an IC697CHS PLC rack. The CPU 731 is programmed and configured by MS-DOS or Windows-based programming software to perform real-time control of machines, processes, and material handling systems. The CPU 731 communicates with I/O and smart option modules over a rack-mounted backplane (IC697CHS750, 782, 783, 790, 791) by way of the VME C.1 Standard format.

Supported option modules include IC697 LAN Interface modules, several Coprocessor modules, 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.

Module operation may be controlled by the three-position switch or remotely by an attached programmer and programming software. CPU status is indicated by three green LEDs on the front of the module.

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

Be sure that power to the PLC is turned off before installing the CPU 731 module

Connect the battery to either of the battery connectors on the module

Put the toggle switch in the STOP position

Install in slot 1 of rack 0

Turn on the power

The module should power up and blink the top LED. When the diagnostics have completed successfully, the top LED stays on and the second and third LEDs are off. The CPU is now ready to be programmed. After the program has been verified, the toggle switch may be moved to the appropriate operation mode position. The LEDs indicate the position of the toggle switch, memory protection status, and the state of the program.

Programmer Connection, Ethernet TCP/IP:

Connecting your programmer via an Ethernet TCP/IP network requires installation of an Ethernet Interface module in the PLC. This can be either the Ethernet Controller, IC697CMM741, or Ethernet Interface (Type 2), IC697CMM742. Before connecting your programmer and PLC to the Ethernet TCP/IP network, you must set the IP address in the Ethernet Interface. After setting the IP address, connect the PLC and the programmer running Windows software to the Ethernet Interface. For more detailed information on the programmer connection via Ethernet TCP/IP, refer to the TCP/IP Ethernet Communications (Type 2) User's Manual and the Windows programming manual, GFK-1295.

Configuration:

The IC697 CPU and I/O system are configured with MS-DOS or Windows-based programming software. There are no DIP switches or jumpers used to configure the system. The CPU verifies the actual module and rack configuration at power-up and periodically during operation. The actual configuration must be the same as the programmed configuration. Deviations are reported to the CPU alarm processor function for configured fault response. Consult Reference 1 for a description of configuration functions.
