IC697PCM711 GE Series 90-70 Coprocessor Unit
Product Introduction
The IC697PCM711 belongs to the GE Fanuc Series 90-70 PLC family. This single-slot coprocessor occupies just one VME backplane position. Its main purpose is to offload intensive tasks from the primary PLC CPU. Consequently, the system responds faster and operates more efficiently. This module supports dual-tasking and handles operator interfaces, complex math, and data logging with ease. Additionally, it communicates directly through the backplane, so no extra application program is necessary. This design simplifies integration and saves development time. For larger applications, the IC697PCM711 accepts expansion memory daughterboards, letting you scale memory as needed.
Memory and Expansion Capabilities
The IC697PCM711 includes 95 KB of base user memory. This capacity suits many standard coprocessor jobs. For more demanding projects, you can install an optional daughterboard. This addition increases total memory to 64 KB, 128 KB, 512 KB, or even 2586 KB, depending on your choice. Furthermore, the module features battery-backed retention. Under normal conditions, it preserves all stored data for up to 6 months without power. This feature protects critical programs during outages or maintenance. Moreover, the module's shelf life reaches 10 years at 20°C (68°F), demonstrating its long-term durability.
Power Requirements and Connectors
The IC697PCM711 draws only 1.0 Ampere from the 5V DC backplane. This low current demand makes it compatible with most Series 90-70 racks. Therefore, you do not need to upgrade your power supply. The module provides two external connectors, labeled 3PL and 4PL. These ports support connections to external devices and programming tools. For configuration, simply connect an IC647 or IC640 computer. Alternatively, you can use any standard IBM-compatible PC running the appropriate software.
Installation Steps
Installing the IC697PCM711 follows a clear sequence. First, disconnect all power from the rack. Next, insert the module into any available single slot on the backplane. If you plan to use an expansion memory daughterboard, attach it to the module before insertion. Then, connect the backup battery to either the 3PL or 4PL connector, following your system design. After that, power up the rack and verify proper recognition. Finally, program and configure the module using your connected PC. The module works perfectly without the daughterboard, offering flexibility for simpler applications.
Typical Use Cases
The IC697PCM711 excels in several critical areas. For instance, it performs real-time mathematical computations without slowing the main CPU. Specifically, it handles operator interface functions, driving local displays or keypads. Moreover, it manages data acquisition and storage, logging process values for analysis. Additionally, the module supports custom communication protocols that require dedicated processing power. Because it runs independently, the IC697PCM711 effectively acts as a secondary processor. As a result, the overall PLC system gains enhanced performance and responsiveness.

Frequently Asked Questions (FAQ)
1. Can I use the IC697PCM711 without the expansion memory daughterboard?
Yes, absolutely. The module runs perfectly with its base 95 KB memory. You only need the daughterboard for larger programs or data sets.
2. Which computers support programming for this module?
You can use an IC647 or IC640 computer. Additionally, any standard IBM-compatible PC with the right development software works fine.
3. How does the IC697PCM711 communicate with the main PLC CPU?
It communicates directly through the VME backplane. This method requires no extra cables or application-level support.
4. What happens if the backup battery runs out?
The memory retains data for up to 6 months without power. After that, you may lose stored information. Therefore, we recommend replacing the battery during routine maintenance.
5. Is this module compatible with all Series 90-70 racks?
Yes, it fits any standard Series 90-70 VME slot. Just ensure your rack's power supply can deliver the required 1.0 A at 5V DC.
