FUNCTIONAL DESCRIPTION:

IC697CPX772 is a 32-Bit Point Single Slot CPU Module manufactured and designed by General Electric as part of the Mark II Series used in GE Speedtronic Control Systems. The CPU module is powered by an 80486DX4 microprocessor running at 96 MHz, offering robust performance for industrial control applications. It features three independent serial ports, accessible from the front of the module, which can be used to connect serial devices or programming terminals. Port 1 utilizes the RS-232 protocol and comes with a 6-pin RJ-11 connector. Port 2 and Port 3 both support the RS-485 protocol, but with a key difference: Port 2 is optocoupler isolated, providing added protection, while Port 3 is not isolated. Port 2 uses a 15-pin female D-connector. The module operates on a 5V DC power supply and has a current consumption rating of 3.1 Amps. It is designed to function within a temperature range of 32�F to 140�F (0�C to 60�C), making it suitable for various industrial environments. For cooling, it supports three types of rack fan assemblies: 120V AC, 240V AC, and 24V DC-powered options.

The CPX772 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.

INSTALLATION:

It is the responsibility of the OEM, system integrator, or end user to 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 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.

• Before powering the system, connect the backup battery to one of the two available battery connectors on the module. This battery provides power to retain user memory, such as programs and configuration data, during power outages or when the system is turned off. Ensure the connection is secure and that the battery is properly seated to avoid memory loss.

• The toggle switch on the module controls the operating state of the CPU. By placing it in the STOP position, you prevent the processor from executing any programs during installation. This ensures that the system remains inactive, avoiding unexpected behavior or damage during the hardware setup.

• The key switch controls memory write protection. By switching it to the OFF position, you allow changes to be made to the CPU's memory, including downloading programs or modifying configuration settings. This is necessary when initializing the module or updating application logic. Once setup is complete, you can switch it back ON to protect the memory from unintended changes.

• For safety and to prevent electrical damage, make sure that the rack is completely powered down before installing the module. This eliminates the risk of short circuits, component damage, or personal injury during hardware installation.

• Once the module is securely installed and all the previous steps are completed, restore power to the rack. The CPU will begin its initialization process. You can then proceed with configuration or program download using your programming device.

The module should power up, and the top left (OK) LED should blink. When the diagnostics have been completed successfully, the top left LED stays on, and the second (RUN) and third (EN) LEDs are off. The fourth (bottom left) LED (MEM PROTECT) is off if the keyswitch is in the OFF position. The CPU is now ready to be programmed (if connected in parallel, the CPU can be programmed regardless of key position). After the program has been verified, the toggle switch can be moved to the appropriate operation mode position: RUN WITH OUTPUTS ENABLED, RUN WITH OUTPUTS DISABLED, or STOP. The seven LEDs indicate the position of the toggle switch, memory protection status, status of serial port activity, and the state of the program.

CONFIGURATION:

The IC697 CPU and I/O system is configured with MS-DOS or Windows-based programming software, although the MS-DOS software does not support all features, such as Bulk Memory Area (BMA), which requires the Windows software version 2.2 or later. See the IPI shipped with this module for programming software feature support details. 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. Refer to the applicable Programming Software User�s Manual for a description of configuration functions.

FREQUENTLY ASKED QUESTIONS:

Can it be programmed with standard PLC languages?

Yes, most modules of this type support programming using IEC 61131-3 standard languages, including Ladder Diagram (LD), Structured Text (ST), Function Block Diagram (FBD), Instruction List (IL), and Sequential Function Chart (SFC). This flexibility makes integration with existing control systems straightforward.

What communication protocols are supported?

These modules typically support a wide range of communication protocols, such as Modbus RTU/TCP, Ethernet/IP, Profibus, Profinet, CANopen, and RS-232/RS-485. This ensures compatibility with various industrial networks and allows for easy integration with other automation devices.

What is the difference between a single-slot and multi-slot CPU module?

A single-slot CPU module contains all necessary processing and communication components within one compact unit, making it ideal for space-constrained applications. In contrast, multi-slot configurations may use additional slots for extended memory, separate communication interfaces, or specialty modules, offering greater expansion but requiring more physical space.
