The Festo CPX-FB33 is a robust bus node designed to connect CPX automation terminals to PROFINET RT and IRT networks. It provides two 4-pin, D-coded M12 fieldbus interfaces and supports data transmission at 100 Mbit/s, enabling reliable communication between pneumatic and electrical modules and the wider control system.
Operating from a nominal 24 V DC supply, the CPX-FB33 offers channel- and module-based diagnostics, configurable failsafe behaviour, status indication through integrated LEDs and access to acyclic process data. Its die-cast aluminium housing provides IP65 and IP67 protection, making it suitable for demanding industrial environments. The unit measures 50 × 107 × 50 mm, weighs approximately 280 g and supports up to 64 bytes each for input and output addressing.

What type of industrial component is this?
The CPX-FB33 is a fieldbus node designed to connect a Festo CPX terminal to an industrial Ethernet network using PROFINET RT or PROFINET IRT.
Which communication protocols does the bus node use?
It communicates using PROFINET RT and PROFINET IRT, with a data transmission rate of 100 Mbit/s.
What network connections are provided?
The unit has two 4-pin, D-coded M12x1 sockets. The two-port arrangement allows it to be incorporated into suitable industrial Ethernet network topologies.
What operating voltage does the unit require?
It has a nominal operating voltage of 24 V DC and an operating range of 18 to 30 V DC. Typical intrinsic current consumption is 120 mA.
What diagnostic information can it provide?
The bus node provides channel- and module-oriented diagnostics, including module undervoltage monitoring and diagnostic memory. LEDs indicate network activity, network errors, system errors, power conditions and parameter status.
How much input and output data can it handle?
The maximum address volume is 64 bytes for inputs and 64 bytes for outputs.
What are its physical dimensions?
Including the interlinking block, the unit measures approximately 50 mm wide, 107 mm long and 50 mm high.
What environmental protection does the enclosure provide?
The enclosure is rated IP65 and IP67 when correctly installed with suitable connections and sealing components.
What temperature range is suitable for operation?
The specified ambient operating temperature range is -5°C to 50°C. The storage temperature range is -20°C to 70°C.
What is the enclosure made from?
The housing is manufactured from die-cast aluminium, providing a robust enclosure for industrial installations.
How is the bus node configured locally?
Local settings are made using integrated DIL switches. An optional memory card can also be fitted for compatible configuration requirements.
What additional communication functions are available?
The CPX-FB33 provides acyclic data access through the fieldbus and Ethernet interfaces, Fast Start Up, channel-oriented diagnostics and representation of system status through process data.
What should be checked before replacing an existing unit?
Confirm the network protocol, connector type, address requirements, DIL-switch positions, power supply range and CPX terminal configuration. Matching these details helps ensure the replacement operates as intended.
What does the network activity indication show?
Separate TP1 and TP2 indicators display network activity for ports 1 and 2. An NF indicator identifies a network fault condition.
How much does the bus node weigh?
The specified product weight is approximately 280 g.
