CI820V | ABB | System 800xA Communication Interface Module

Product Description

System Communication and Network Architecture

The CI820V (Part Number: CI820V) is a high-performance Profibus-DP Communication Interface module specifically engineered for the ABB AC 800M controller family within the System 800xA architecture. Functioning as a high-speed bridge, the CI820V (Model: CI820V) enables the AC 800M CPU (such as PM861 or PM864) to interface seamlessly with Profibus-DP V0 and V1 fieldbus networks. This module is critical for distributed control scenarios, allowing the central controller to manage remote I/O stations, frequency converters, and intelligent field devices with deterministic timing. By offloading communication overhead from the main CPU, it ensures that process control logic remains responsive even in high-traffic network environments.
