Description

The ABB 07KT98 (often referenced with variant code WT98 and Order Code GJR5253100R3262 or similar) is a sophisticated communication basic module designed for the ABB AC31 PLC series, specifically the powerful AC31-90 family. This module serves as a high-performance gateway, enabling seamless integration of AC31 controllers into modern industrial networks via Ethernet TCP/IP and CANopen protocols. By providing dual-protocol support, the 07KT98 allows legacy AC31 systems to communicate with modern SCADA systems, HMIs, drives, and remote I/O stations, effectively future-proofing automation infrastructure without requiring a complete controller replacement.

Application Scenarios

A food and beverage packaging facility faced significant challenges integrating their existing AC31-90 control system with a new enterprise-level MES (Manufacturing Execution System) that required real-time Ethernet data exchange. The legacy CS31 bus was insufficient for the required bandwidth, and adding a separate gateway introduced latency and complexity. By installing the ABB 07KT98 module directly into the AC31-90 rack, the plant established a native Ethernet connection. The 07KT98 facilitated high-speed data transfer of production counts, quality metrics, and alarm states to the MES while simultaneously managing a CANopen network of new servo drives on the packaging line. This dual-protocol capability of the 07KT98 eliminated the need for multiple gateways, reduced wiring costs by 40%, and improved data update rates from seconds to milliseconds, ensuring precise synchronization between packaging robots and the central management system.
