PHOENIX CONTACT RFC470 PN 3TX – PROFINET IO Controller | Inline Controller Platform
Engineering Background
The PHOENIX CONTACT RFC470 PN 3TX is a high-performance PROFINET IO Controller designed for demanding industrial automation environments. Built on PHOENIX CONTACT’s proven Inline Controller platform, this module delivers deterministic real-time communication across PROFINET networks with three integrated 100 Mbit/s TX ports, enabling flexible ring, line, and star topologies without additional switching hardware.
Product Positioning
Targeted at OEM machine builders, system integrators, and plant automation engineers, the RFC470 PN 3TX bridges the gap between compact PLC functionality and enterprise-grade PROFINET IO management. It supports IEC 61131-3 programming environments and is fully compatible with PHOENIX CONTACT’s PC WORX and PC WORX Engineer software suites, making it the preferred choice for engineers standardizing on PHOENIX CONTACT ecosystems.

Proven Application Environments
- Automotive Manufacturing: Body-in-white assembly lines requiring deterministic PROFINET IRT communication with sub-millisecond jitter tolerance.
- Packaging Machinery: High-speed pick-and-place systems where the RFC470’s MRP ring topology ensures zero-downtime network redundancy.
- Water & Wastewater Treatment: Remote I/O expansion across distributed pump stations using PROFINET IO RT with long cable runs.
- Oil & Gas Skid Automation: ATEX Zone 2 rated installations requiring certified PLC controllers with integrated fieldbus management.
- Building Automation & HVAC: Multi-zone control architectures leveraging the three TX ports for segmented network zones.
Engineering Advantages
- 3-Port Integrated Switch: Eliminates the need for an external managed switch in line and ring topologies, reducing panel footprint and BOM cost.
- MRP Ring Redundancy: Media Redundancy Protocol support provides <200 ms network recovery, meeting IEC 62439-2 requirements for high-availability systems.
- Inline Bus Integration: Direct connection to PHOENIX CONTACT Inline I/O modules without additional gateways — simplifies wiring and reduces commissioning time.
- IEC 61131-3 Compliance: Full five-language PLC programming support enables code reuse across PHOENIX CONTACT controller families.
- Compact DIN Rail Form Factor: Optimized for space-constrained control cabinets with standard 35 mm DIN rail mounting.
- Broad Certification Portfolio: CE, UL, cUL, and ATEX Zone 2 certifications support global machine export compliance.
System Architecture & Signal Flow
The RFC470 PN 3TX operates as the PROFINET IO Controller (master) on the PROFINET network. The integrated 3-port 100BASE-TX switch allows the controller to simultaneously manage upstream SCADA/HMI communication and downstream IO device networks without external switching hardware. On the local bus side, the RFC470 connects directly to PHOENIX CONTACT Inline I/O terminals via the proprietary Inline bus connector, providing deterministic local I/O scanning independent of the PROFINET cycle. The controller executes IEC 61131-3 application programs cyclically, mapping local Inline I/O data and remote PROFINET IO device data into a unified process image for the application program.

Technical FAQ
Q: Is the RFC470 PN 3TX compatible with SIMATIC STEP 7 or TIA Portal?
A: No. The RFC470 PN 3TX is programmed exclusively with PHOENIX CONTACT PC WORX or PC WORX Engineer software. It is not compatible with Siemens programming environments.
Q: Can the RFC470 PN 3TX act as a PROFINET IO Device (slave)?
A: No. The RFC470 PN 3TX is a PROFINET IO Controller (master) only. For IO Device functionality, refer to PHOENIX CONTACT’s BK series bus couplers.
Q: What is the maximum number of PROFINET IO devices supported?
A: Up to 64 PROFINET IO devices can be connected to a single RFC470 PN 3TX controller.
Q: Does the RFC470 PN 3TX support PROFINET IRT (Isochronous Real-Time)?
A: Yes, the RFC470 PN 3TX supports both PROFINET RT and IRT communication classes, enabling motion control and high-precision synchronization applications.
Q: What firmware version is shipped?
A: Units are shipped with the firmware version as received from the manufacturer or as verified during incoming inspection. Firmware upgrade support is available upon request.
Q: Is a GSDML file available for integration with third-party PROFINET controllers?
A: The RFC470 PN 3TX is a PROFINET IO Controller, not a device. GSDML files are not applicable. For integration as an IO device in a third-party system, please consult PHOENIX CONTACT technical support.
