GE IC670CHS001E

Description

Product Description

The GE IC670CHS001E is a specialized high-speed serial communication module for the GE Fanuc Series 90-30 programmable logic controller (PLC). This module is a High-Speed Serial (HSS) Communications Co-processor designed to provide deterministic, peer-to-peer data exchange between multiple Series 90-30 controllers over a dedicated serial link. Its primary function is to enable tightly coupled control applications where separate PLCs need to share large amounts of data with minimal latency and high reliability. The GE IC670CHS001E facilitates the creation of a unified control environment across multiple PLCs, allowing for the distribution of complex control tasks. Using a robust serial protocol over a direct cable connection, this module ensures fast and coordinated data transfer essential for synchronized machine control. Implementing the GE IC670CHS001E is key for building advanced, multi-controller automation systems that require precise coordination, such as in material handling or complex assembly lines.

Product Parameters

• PLC Family: GE Fanuc Series 90-30.
• Module Type: High-Speed Serial (HSS) Communications Co-processor Module.
• Communication Protocol: Proprietary GE high-speed deterministic protocol for global data exchange.
• Interface: RS-422/485 (typically using a 9-pin D-sub connector).
• Data Transfer Rate: High-speed (e.g., up to 115.2 kbps or higher), configurable for optimal performance.
• Topology: Point-to-point link between two GE IC670CHS001E modules in different PLC racks.
• Function: Extends the controller’s global data memory to another Series 90-30 PLC, creating a single logical controller from two physical units.
• Maximum Distance: Supports separation of several hundred feet with proper cabling.
• Configuration: Used in pairs (one module per PLC rack). Configured via the Series 90-30 programming software.
• Status Indicators: LEDs for power, transmit/receive activity, and fault conditions.

Advantages and Features

• Deterministic, High-Speed Performance: Provides low-latency, predictable data exchange between controllers, enabling tightly coordinated control across distributed processors.
• Simplified Multi-CPU Programming: Creates a unified global data table shared between the connected PLCs. Data produced in one PLC is instantly available to logic in the other without complex messaging programming.
• Reduced Network Complexity: Offers a dedicated, point-to-point link for critical data sharing, avoiding potential congestion or determinism issues on a shared plant network (e.g., Ethernet).
• Reliable Industrial Design: The RS-422/485 interface provides good noise immunity for reliable communication in typical industrial settings.
• Cost-Effective Coordination: Provides a method for high-performance coordination between two Series 90-30 CPUs without requiring a more expensive, single high-end controller.

Application Cases in Application Fields

• Packaging Lines with Multiple Stations: Synchronizes two Series 90-30 controllers, one managing the infeeder and filler, the other controlling the capper and labeler, ensuring seamless product transfer.
• Material Handling Conveyor Systems: Coordinates separate PLCs controlling different zones of a large conveyor system for smooth package flow and sortation.
• Assembly Machines with Multiple Cells: Allows a master PLC to share assembly data and sequences with a subordinate PLC controlling a robotic cell.
• Test Stands with Separate Control and Data Acquisition: Links a control PLC to a data logging PLC for synchronized operation and high-speed data transfer.

Comparisons with Competing Products

• Vs. Series 90-30 Genius Bus Communication (CMM321): The Genius bus is for connecting to remote I/O and peer messaging. The GE IC670CHS001E is designed for much higher-speed, lower-latency, and larger-volume data sharing between two controllers themselves, representing a different tier of communication.
• Vs. Ethernet Global Data (EGD) over Ethernet Modules: Later Series 90-30 Ethernet modules could use EGD. The GE IC670CHS001E offers a more deterministic, dedicated hardware solution less susceptible to network traffic issues, though at a lower bandwidth than modern Ethernet.
• Vs. Siemens S7-300 with Global Data Exchange via MPI: Siemens used the MPI network for a similar purpose. The GE IC670CHS001E provides a dedicated communication channel, while MPI is a shared network. Both serve to create a shared data area between CPUs.

Selection Suggestions and Precautions

1. Dedicated Point-to-Point Use: The GE IC670CHS001E is designed exclusively for connecting two Series 90-30 CPUs. It cannot be used in a multi-drop network or for connecting to devices other than another Series 90-30 with the same module.
2. Correct Cabling and Termination: Use a high-quality, shielded twisted-pair cable wired for RS-422/485 operation. Ensure proper termination at both ends if required by the module’s specifications to prevent signal reflections.
3. Configuration in Programming Software: Both modules in the pair must be correctly configured in the Series 90-30 hardware configuration within the programming software (Proficy Machine Edition). The global data tables must be sized and mapped identically in both CPUs.
4. Baud Rate and Parameter Matching: Ensure the communication parameters (baud rate, parity, etc.) are identical for both GE IC670CHS001E modules. A mismatch will cause communication failure.
5. Consider Modern Alternatives: For new system designs, consider using a more modern platform (like GE’s PACSystems RX3i) that supports high-speed Ethernet-based data exchange (e.g., SRTP) which offers greater flexibility and bandwidth. The GE IC670CHS001E is a solution for existing Series 90-30 systems.
