Product Description

GE IC697BEM713 90-70 Series Bus Expansion Module

The IC697BEM713 is a Bus Expansion Module in the GE Fanuc 90-70 series PLCs. Similar to the IC697BEM711, it belongs to the bus expansion module category. It is mainly used to extend the bus communication range of PLC systems, support multi-rack distributed architectures, and realize high-speed data interaction between the main controller and expansion racks. The following is a detailed introduction:

Core Function Positioning

As a bus expansion interface of the 90-70 series, the core role of the IC697BEM713 is to extend the VME bus signals of the main rack to expansion racks. It solves the problems of limited number of modules in a single rack or scattered physical locations of equipment, supports the expansion of the system from a "single rack" to a "multi-rack distributed" structure, and ensures real-time data transmission between the main CPU and all expansion modules.

Key Technical Parameters and Characteristics

Bus Type
Based on the VME industrial bus standard, it supports high-speed parallel data transmission. The transmission rate is consistent with that of the main rack bus (up to approximately 40MB/s), meeting the low-latency requirements of real-time control scenarios.
Expansion Capability
It can connect multiple expansion racks (the specific number depends on the system configuration). The maximum distance between racks usually supports about 10 meters (special bus cables are required), which is suitable for scenarios where equipment in the workshop is distributed in a scattered layout.
Communication Function

Realizes bidirectional data transmission between the main rack and expansion racks: including control commands, configuration parameters (from the main CPU to expansion modules) and sensor data, module status (from expansion modules to the main CPU).
Supports multi-rack synchronization: calibrates the operation timing of all expansion racks through bus clock signals to ensure the consistency of the actions of each module (such as synchronous analog acquisition, timing matching of digital output).

Fault Diagnosis and Protection

Built-in self-diagnostic circuit, which can monitor the bus communication status (such as signal loss, transmission errors, rack connection faults).
When a fault occurs, it sends an alarm signal to the main CPU through indicator lights (such as a flashing COM light) or the bus, facilitating quick problem location.
Equipped with anti-interference design: adopts differential signal transmission and electromagnetic shielding, adapting to strong electromagnetic environments in industrial sites (such as near motors and frequency converters).

Mechanical and Installation Characteristics

Adopts a mechanical keying design to ensure that the module is correctly installed in the rack slot, avoiding communication failures caused by incorrect insertion.
Supports hot swapping (some models): allows module replacement during system operation without interrupting the overall control process, improving maintenance convenience.

Differences from IC697BEM711

Both are bus expansion modules of the 90-70 series, with similar core functions, but there may be differences in expansion scale, compatibility, or detailed design (please refer to the official manual for details):

It may support a larger number of expansion racks or be compatible with higher-performance CPU modules.
Some detailed parameters (such as power consumption, bus driving capability) may be slightly different, making it suitable for larger-scale distributed systems.

Typical Application Scenarios

Large industrial production lines: Such as automobile manufacturing, metallurgical steel rolling, etc., where equipment is distributed in multiple workshop areas. Through the IC697BEM713 to expand racks, the main controller can centrally monitor and control scattered equipment.
Complex process control: Such as the linkage of multiple devices in chemical parks and the coordination of multiple units in power systems, which require bus expansion to realize cross-regional data interaction.
High-reliability systems: In key scenarios such as power plants and sewage treatment plants, it can be combined with redundant designs (such as dual buses, dual racks). The IC697BEM713 ensures the stability of the communication link and avoids the impact of single-point faults on the overall system.

Summary

The IC697BEM713 is a key component for building distributed control systems with 90-70 series PLCs. By extending the VME bus and ensuring multi-rack synchronization and communication reliability, it supports the expansion of the system to a larger-scale and more scattered architecture, and is suitable for industrial scenarios with high requirements for real-time performance and stability. The specific configuration needs to be combined with the system scale and official manual to ensure compatibility with other modules (such as CPU, I/O modules).
