Advantages and Features

The primary advantage of the GE IC697PCM711P lies in its ability to offload complex processing tasks from the main PLC CPU, improving overall system performance and response times. By utilizing the GE IC697PCM711P, system integrators can implement sophisticated algorithms, custom protocols, or high-speed control loops that would be difficult or impossible to execute in standard ladder logic. The module operates independently, with the GE IC697PCM711P executing its program in parallel with the main CPU’s scan, providing true multitasking capability within the PLC chassis. Shared memory communication between the GE IC697PCM711P and the main CPU allows seamless data exchange, with the coprocessor reading inputs and writing outputs that appear as normal PLC memory to the ladder program. The serial communication ports on the GE IC697PCM711P provide flexible connectivity to external devices such as bar code readers, printers, scales, or intelligent instruments, offloading these communication tasks from the main processor. For applications requiring custom mathematical functions, statistical analysis, or specialized sequencing, the GE IC697PCM711P provides a powerful platform for implementing solutions in high-level languages.

Application Cases in Application Fields

The processing power of the GE IC697PCM711P makes it valuable across numerous applications requiring specialized computation or communication beyond standard PLC capabilities.

• Automotive Assembly – Torque Control: In an engine assembly line, the GE IC697PCM711P executes precision torque control algorithms for critical fastener installations, monitoring angle and torque in real-time and making micro-adjustments to tool operation that would exceed the scan time capabilities of the main CPU.

• Material Handling – Bar Code Processing: At a high-speed distribution center, the GE IC697PCM711P interfaces directly with bar code scanners, parsing complex shipping labels and looking up routing information in local memory tables, freeing the main PLC for high-speed sortation control.

• Food Processing – Recipe Management: In a batch food mixing facility, the GE IC697PCM711P stores and manages hundreds of product recipes, downloading ingredient quantities and mixing parameters to the main PLC on demand while maintaining audit trails of recipe changes.

• Water Treatment – Chemical Dosing: At a municipal water plant, the GE IC697PCM711P executes advanced process control algorithms for chemical dosing, calculating optimal feed rates based on multiple water quality parameters and flow measurements.

• Packaging – Statistical Process Control: On a high-speed packaging line, the GE IC697PCM711P collects weight data from checkweighers, performs real-time statistical analysis, and automatically adjusts fillers to maintain target weights while minimizing product giveaway.

Comparison with Competing Products

When compared to similar coprocessor or specialized processing modules from other PLC platforms, the GE IC697PCM711P offers specific advantages for users invested in the Series 90-70 ecosystem. While Allen-Bradley’s ControlLogix platform offers various specialty modules for specific functions, the GE IC697PCM711P provides a general-purpose programmable environment that can be customized for virtually any application. Compared to Siemens S7-400 technology CPUs with integrated special functions, the GE IC697PCM711P offers greater flexibility for users willing to develop custom C-language applications. For facilities with existing Series 90-70 infrastructure, the GE IC697PCM711P provides the most direct path to adding advanced processing capabilities without migrating to newer, incompatible platforms. The module’s ability to execute complex algorithms independently of the main PLC scan makes the GE IC697PCM711P ideal for applications where deterministic response or high-speed computation is required.

Selection Suggestions and Precautions

When selecting the GE IC697PCM711P for your application, first verify compatibility with your specific Series 90-70 CPU model and firmware revision, as older CPUs may have limitations in shared memory communication. Ensure that the GE IC697PCM711P has sufficient memory and processing power for your intended application, considering both program size and execution speed requirements. When developing software for the GE IC697PCM711P, use GE’s recommended development tools and follow established practices for C or assembly programming in real-time control applications. Pay careful attention to the interaction between the GE IC697PCM711P and the main CPU, ensuring that shared memory conflicts are avoided through proper handshaking and data consistency mechanisms. When installing the GE IC697PCM711P, verify that the rack power supply has sufficient capacity to support the module’s current draw, particularly if multiple coprocessors are installed in the same rack. Before commissioning, thoroughly test the GE IC697PCM711P program under all expected operating conditions, including edge cases and fault scenarios, to ensure reliable operation. Finally, maintain current backups of both the GE IC697PCM711P program source code and compiled binary to enable rapid recovery in the event of module failure.
