Description

XUD194: Product Overview
The XUD194 is a communication interface module designed for ABB’s AC 800M controller system within the System 800xA platform. This module functions as a PROFIBUS DP (Decentralized Peripherals) Master, enabling the AC 800M controller to communicate with a network of PROFIBUS DP slave devices. Installed in a communication slot of the AC 800M controller baseplate, it serves as the master station on the PROFIBUS DP network, managing cyclic data exchange with configured slave devices according to the PROFIBUS standard.
The module operates by scanning connected slave devices, reading input data from field sensors, and writing output data to actuators based on the controller’s application program. It handles network management functions including token passing, station diagnostics, and baud rate detection. The module supports the full range of PROFIBUS DP baud rates up to 12 Mbps, allowing for optimized network performance based on distance and application requirements. Its design focuses on reliable industrial communication with error detection and recovery mechanisms to maintain network integrity.

Core Features & Customer Value
The module’s PROFIBUS DP Master capability enables distributed I/O architecture, reducing wiring costs and improving system flexibility. For system integrators, this means remote I/O stations can be placed close to field devices while maintaining a single digital communication link back to the main controller. The high baud rate (up to 12 Mbps) ensures fast response times for time-critical applications.
The comprehensive diagnostic capabilities provide detailed information about network status and individual slave devices. Maintenance personnel can quickly identify communication faults, faulty slaves, or cable problems, reducing mean time to repair (MTTR). The module’s hot-swappable capability (in redundant systems) allows for replacement without shutting down the controller, minimizing system downtime during maintenance.
Typical Applications
In automotive manufacturing, the XUD194 communicates with PROFIBUS DP remote I/O modules distributed along a production line. The module reads sensor data from welding robots and writes control signals to pneumatic valves, enabling synchronized operation of the assembly process.
In water treatment plants, the module interfaces with PROFIBUS DP variable frequency drives controlling pump motors. It reads motor parameters and writes speed setpoints, allowing for precise flow control and energy optimization.
