Product Overview: Festo 571339 CPX-FB33 Bus Node
The Festo 571339, specifically the CPX-FB33, is a high-performance bus node designed for the modular CPX terminal system. This component serves as the communication interface between the decentralized CPX terminal and a PROFINET IO network. It is an essential part of modern Industry 4.0 environments, allowing for the seamless integration of pneumatic and electrical I/O modules into high-level control systems.
Advanced Communication and Connectivity
The CPX-FB33 supports the PROFINET IO protocol (Version 2.3) and features an integrated switch with two RJ45 ports, enabling linear or ring network topologies (MRP support). This bus node is capable of transmitting high-speed real-time data and provides extensive diagnostic functions to minimize system downtime. It is designed to withstand harsh industrial conditions with its high ingress protection when fully assembled.
Key Technical Specifications

System Integration and Benefits
Using the Festo 571339 ensures highly flexible automation. The CPX terminal can be expanded with digital inputs, analog outputs, and valve manifolds (like the MPA or VTSA). The CPX-FB33 node manages the power supply and communication for all these components, providing a single point of access for PLC programming. Its «Fast Start-Up» (FSU) capability is particularly useful in robotic tool-change applications where rapid network re-establishment is required.
| Feature | Detail |
| Network Topology | Star, Line, Ring (MRP) |
| Supply Voltage | 24V DC (+/- 25%) |
| Internal Current Consumption | Max. 160 mA |
Maintenance and Safety
The CPX-FB33 features built-in LED indicators for rapid fault detection regarding network status and module errors. When replacing a node, the modular design of the CPX system allows for easy physical swapping while the configuration can be automatically re-downloaded from the PLC, ensuring rapid serviceability.
