GE IC697PCM711 single-slot programmable coprocessor module

I. Computing and Processing Performance

Dual-tasking capability

It is equipped with a built-in dual-task module, which can execute real-time computing and data processing tasks

 (such as complex logical operations and mathematical function calculations) in parallel, reducing the load on the main

 CPU and improving the system response speed.

Typical application scenarios: Real-time processing of sensor data (such as temperature and pressure signals) in

 industrial automation, and simultaneous execution of control logic output.

Data processing efficiency

Supports high-speed data acquisition and storage, capable of real-time processing of analog/digital input and output

 (such as analog-to-digital conversion of current and voltage signals), and is suitable for scenarios requiring 

high-frequency sampling (such as motor speed monitoring).

It has the functions of data buffering and preprocessing, reducing the data interaction frequency of the main CPU and 

optimizing the overall throughput of the system.

Ii. Storage and Memory Performance

Basic storage configuration

It is equipped with a standard user memory of up to 95KB, which is used to store program codes, configuration 

parameters and operation data, meeting the storage requirements of small and medium-sized control programs.

Supports non-volatile storage (such as battery backup) to ensure data is not lost after power failure, and is suitable for 

scenarios where continuous recording of operating status is required (such as equipment failure logs).

Expand storage capacity

The storage capacity can be expanded to 64KB, 128KB, 512KB or 2586KB by extending the memory sub-board, which is 

suitable for large-scale programs or the storage requirements of massive data (such as historical trend data recording).

It supports the connection of up to 512KB of external expansion memory, further enhancing the flexibility of data storag

e. It is suitable for industrial monitoring systems that require long-term preservation of operational data.

Iii. Communication and Compatibility Performance

Backplane communication efficiency

It communicates directly with the main CPU of the PLC through the backplane bus without the need for additional 

application support. The communication latency is low (typical value <1ms), ensuring control scenarios with high 

real-time requirements (such as high-speed production line linkage).

It supports multi-module parallel communication and can be seamlessly integrated with other I/O modules (such as 

the IC697 series digital and analog modules) to build complex control systems.

Protocol and interface compatibility

Compatible with the communication protocol of the GE Fanuc 90-70 series, it can interact data with the upper 

computer (such as the SCADA system) or other PLC devices through standard protocols (such as Modbus, TCP/IP).

Communication interface parameters (such as baud rate, data bits, and verification methods) can be customized 

through programming to meet the access requirements of devices from different manufacturers.

Iv. Reliability and Environmental Adaptability

Industrial-grade anti-interference design

Insulation resistance: ≥2MΩ at DC 500V to prevent leakage from affecting the stability of the module.

Anti-noise capability: It can withstand 1000V, 1μS pulse interference for 1 minute and is suitable for industrial sites with 

strong electromagnetic interference (such as near frequency converters and motors).

Environmental adaptability

Operating temperature range: 0-60℃, it can operate stably in high-temperature environments (such as metallurgical 

and chemical workshops).

Humidity adaptability: 5%-95% (no condensation), suitable for humid environments (such as offshore platforms, food 

processing workshops);

Vibration resistance: Complies with industrial standards (such as IEC 60068-2-6), and can resist mechanical vibration 

during the operation of equipment.

V. Power Supply and Power Consumption Performance

Power requirement: Only a 5V bus is needed to provide 1A power, with low power consumption (typical value <5W), 

reducing the overall energy consumption of the system. It is suitable for scenarios sensitive to power consumption 

(such as distributed control systems).

Power supply stability: It is equipped with overvoltage and undervoltage protection functions. When the power supply 

fluctuates, it automatically protects the module hardware to prevent faults caused by abnormal voltage.

Six. Programming and Configuration flexibility

Compatibility of development tools

It supports program development and configuration through GE Fanuc dedicated programming software (such as 

VersaPro, Cimplicity Machine Edition), and can also be accessed for programming through IBM-compatible PCS or

 IC647/IC640 computers.

It supports multiple programming languages such as ladder Diagram (LD) and Structured Text (ST), meeting the 

development habits of different engineers.

Custom logic function

Data processing algorithms (such as filtering, PID control), communication protocol conversion or human-machine

 interface logic can be customized through programming, flexibly adapting to special process requirements (such as 

temperature cascade control of chemical reaction vessels).

Vii. Typical Performance Application Scenarios

High-speed data acquisition system

In photovoltaic power stations, voltage and current data of multiple solar panels are collected in real time, and power 

calculation and MPPT (Maximum Power Point Tracking) control are carried out, with a response time of less than 10ms.

Complex motion control

In machine tool processing equipment, the coprocessor independently processes the position and speed feedback data

 of the servo motor, and collaborates with the main CPU to complete high-precision interpolation operations. The 

positioning accuracy can reach ±0.01mm.

Condition monitoring of large-scale equipment

In the blast furnace of steel metallurgy, historical data of temperature and pressure collected by sensors (sampling 

frequency 100Hz) are stored and analyzed. Through trend analysis, equipment failures are predicted and early warnings

 are issued.

Summary

The core performance advantage of IC697PCM711 lies in its ability to provide "computing acceleration + data 

optimization" for industrial control systems through dual-task processing, expanded storage and efficient 

communication. It is particularly suitable for scenarios that require real-time performance, high reliability and flexible 

configuration. Its industrial-grade design and low power consumption characteristics further ensure stable operation 

under complex working conditions, and it is a key module for improving the overall performance in the GE 90-70 series

 PLC system.
