Emerson A6824 ModBus and Rack Interface Module

Emerson A6824 ModBus and Rack Interface Module

Functional Description

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 6500 modules and outputs these parameters via ModBus

TCP/IP and/or ModBus RTU (serial). This 1-slot monitor is used together with other AMS 6500 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 can be configured, or for redundant paths, can be used

simultaneously.

The AMS 6500 is an integral part of PlantWeb® and AMS software. PlantWeb provides operations integrated

machinery health combined with the Ovation® and DeltaV™ process control system. AMS software provides

maintenance personnel advanced predictive and performance diagnostic tools to confidently and accurately

determine machine malfunctions early.
