1. Product Overview

2. Key Technical Parameters

3. Product Features

• High Integration: The card integrates a LAN Control Processor (LCP) and dual-port RAM internally, which significantly improves the real-time performance and stability of data transmission.
• Redundant Design: Some models support multi-segment redundancy, ensuring that the system can still operate normally in case of network failure, which greatly improves the reliability of the DCS system.
• Flexible Compatibility: Compatible with various models of drives and exciters in the GE Fanuc series, suitable for the transition from old system upgrades to new systems.
• Easy Maintenance: Provides a removable EPROM memory cartridge, which facilitates the upgrade and maintenance of LCP programs.

4. Structure and Composition

• LAN Control Processor (LCP): Responsible for the processing of the network protocol stack and the routing and forwarding of data.
• Dual-port RAM: Serves as a buffer to buffer the data flow between the CPU and external I/O.
• Network Interface Module: Includes RJ45 interface and related PHY chips.
• Power Management Module: Responsible for the internal power supply of the communication card, which is usually provided uniformly by the system power supply.

6. Installation and Maintenance

Installation Steps

1. Hardware Access: Install the communication card into the corresponding PCI/PCIe slot of the DCS control cabinet (please refer to the on-site wiring diagram for the specific slot position).
2. Network Connection: Use shielded twisted-pair cables (Cat5e/6) to connect the RJ45 interface of the card to the on-site industrial switch or field bus (such as DLAN network).
3. Software Configuration: Load the corresponding driver in the DCS control system and configure network parameters (IP address, subnet mask, gateway, etc.).

Maintenance Points

1. Firmware Upgrade: Through the upgrade function of the DCS system, upgrade the firmware version of the LCP to the latest to fix potential communication vulnerabilities.
2. Interface Inspection: Regularly check the contact status of the RJ45 interface, clean up dust, and prevent network disconnection caused by poor contact.
3. Log Monitoring: Through the log function of the DCS system, monitor the error codes and alarm information of the communication card, and handle network abnormalities in a timely manner.
