Emerson A6500-CC System Communication Card AMS 6500 ATG

The ModBus and Rack Interface Module is designed for high reliability for the plant's most critical rotating machinery. It reads parameters from all AMS A6500 ATG modules and outputs these parameters through ModBus TCP/IP and or ModBus RTU (serial).

In addition, OPC UA is available for data transmission to third party systems. This 1-slot monitor is used together with other AMS A6500 ATG monitors to build a complete API 670 machinery protection monitor. Applications include steam,gas, compressors, and hydro turbo machinery.

Operators are provided machinery health parameters in the control environment for seamless integration. The module powers local graphical displays at the protection rack for machine and instrumentation readout. Either ModBus TCP/IP or ModBus RTU or OPC UA can be configured, or for redundant path, can be used simultaneously.

EMERSON A6500-CC AMS 6500 ATG System Communication Card

1. Product Overview

The A6500-CC is a communication interface card specifically designed for Emerson's AMS 6500 ATG (Automatic Tank Gauging) system. Its primary function is to extend the communication capabilities of the central control unit (A6500-UM), serving as a critical bridge connecting the entire tank gauging system to external systems such as central control rooms, SCADA systems, and inventory management platforms.

2. Key Functions and Roles

Protocol Conversion and Interface Expansion: This card provides additional physical communication interfaces and protocol support, enabling the AMS 6500 system to seamlessly integrate with third-party systems using different industrial protocols.

Remote Data Transmission: Acting as the system's "gateway," it reliably transmits all processed tank data (level, temperature, volume, alarm status, etc.) from the control unit (A6500-UM) to upper-level management systems.

High-Reliability Design: Engineered for industrial environments, it ensures stable and continuous data communication under harsh conditions, meeting the high reliability requirements of the storage and transportation industry.

3. Common Communication Protocols and Interfaces

The A6500-CC communication card typically supports multiple industry-standard protocols, depending on the hardware version and configuration. Common protocols include:

Modbus TCP/IP: The most widely used protocol for integration with SCADA, DCS, or PLC systems via Ethernet interfaces.

Modbus RTU/ASCII: Communication via RS-232 or RS-485 serial interfaces.

OPC (DA/UA): Functions as an OPC server or client to exchange data with OPC-supported client applications (e.g., historical databases, MES systems).

EtherNet/IP: A universal protocol suitable for PLC systems such as Rockwell Allen-Bradley.

4. Typical Application Scenarios

Within the AMS 6500 rack, the A6500-CC communication card works in synergy with the A6500-UM universal measurement control card:

A6500-UM (The Brain): Responsible for connecting and managing all tank gauge sensors, performing data acquisition, calculations, and alarm judgment.

A6500-CC(The Messenger): Responsible for receiving data from the A6500-UM, converting it into the appropriate protocol format, and transmitting it via Ethernet or serial lines.

This architecture separates data processing and communication tasks, enhancing overall efficiency and reliability.
