Overview
The A6500-CC is a system communication card for the AMS A6500 ATG machinery protection platform. It reads parameters from the installed ATG monitor modules and transfers machinery condition data to external systems through Modbus TCP/IP, Modbus RTU over serial communication, and OPC UA. The card also supports local graphical displays at the protection rack and can provide multiple communication paths simultaneously when configured.
Key Features
- Reads parameters from AMS A6500 ATG monitor modules.
- Supports Modbus TCP/IP and Modbus RTU serial communication.
- Provides OPC UA for data exchange with third-party systems.
- Supports simultaneous communication protocols for redundant data paths.
- Powers local graphical displays for machinery and instrumentation readout at the protection rack.
- Occupies one slot in the monitoring system.
- Forms part of an API 670 machinery protection monitoring configuration when used with other AMS A6500 ATG monitors.

Communication and Data Integration
The A6500-CC collects measurement and status parameters from the AMS A6500 ATG monitor modules and makes them available to external control, monitoring, and data acquisition systems. Modbus TCP/IP provides Ethernet-based communication, while Modbus RTU supports serial communication over RS-485. OPC UA provides an additional interface for exchanging data with third-party systems.
The communication configuration can use Modbus TCP/IP, Modbus RTU, or OPC UA. The supplied product description also states that these paths can operate simultaneously for redundant communication arrangements. The required protocol configuration should match the receiving system and the intended communication architecture.
Application in Machinery Protection Systems
The card works with other AMS A6500 ATG monitors as part of a machinery protection monitoring system designed around API 670 requirements. It transfers monitor parameters to the plant control environment, allowing operators to access machinery health information alongside other process data.
In addition to external data communication, the A6500-CC supports local graphical displays at the protection rack. This function allows machine and instrumentation readings to be presented locally without relying solely on an external control system display.
Frequently Asked Questions
Q: Which communication protocols does the A6500-CC support?
A: It supports Modbus TCP/IP, Modbus RTU over serial communication, and OPC UA. The selected configuration depends on the connected system and communication requirements.
Q: Can the A6500-CC provide redundant communication paths?
A: The supplied description states that multiple communication paths can operate simultaneously for redundancy. The actual path arrangement and protocol configuration must be confirmed for the intended system.
Q: Is the A6500-CC a standalone machinery protection monitor?
A: No. The supplied description identifies it as a system communication card that works with other AMS A6500 ATG monitor modules. It collects and transfers their parameters and supports local graphical displays.
