PHOENIX CONTACT RFC 430 ETH-IB 2730190 – Ethernet/InterBus Remote Field Controller | ILC 2050 BI Platform
Engineering Background
The RFC 430 ETH-IB belongs to Phoenix Contact’s ILC 2050 BI controller family — a platform engineered for distributed I/O architectures where deterministic fieldbus communication and Ethernet connectivity must coexist. Designed for mid-to-large automation cells, this controller bridges INTERBUS ring topology with standard Ethernet infrastructure, enabling seamless integration into modern SCADA and DCS environments without sacrificing legacy fieldbus investments.
Product Positioning
Targeted at procurement engineers and system integrators managing industrial control upgrades, the RFC 430 ETH-IB (Part No. 2730190) delivers a proven, OEM-sourced solution for applications demanding high-speed cyclic I/O, robust diagnostics, and dual-network flexibility. It is a direct fit for automotive assembly, process automation, and material handling systems already running INTERBUS segments.

System Architecture & Signal Flow
The RFC 430 ETH-IB operates as the INTERBUS master, managing a ring-topology fieldbus network. Field devices (sensors, actuators, remote I/O stations) connect via INTERBUS segments. The controller’s Ethernet port connects upstream to the plant network, SCADA server, or engineering workstation. Cyclic process data is exchanged between the INTERBUS ring and the Ethernet layer through the controller’s internal memory map, with configurable mapping via PC Worx project configuration. The onboard SD card slot supports project backup and firmware updates without a PC connection on-site.

Technical FAQ
Q: Is the RFC 430 ETH-IB compatible with PC Worx programming software?
A: Yes. The RFC 430 ETH-IB is programmed using Phoenix Contact’s PC Worx IEC 61131-3 IDE. Existing PC Worx projects from other ILC 2050 BI controllers can typically be migrated with minor hardware configuration adjustments.
Q: Can this controller replace an RFC 430 ETH (without IB suffix)?
A: The RFC 430 ETH-IB adds INTERBUS master functionality. If your application does not use INTERBUS, the RFC 430 ETH may be sufficient. Confirm your fieldbus topology before substitution.
Q: What is the maximum INTERBUS cable length?
A: Per INTERBUS specification, the total ring cable length can reach up to 400 m per segment (RS-485 physical layer). Refer to Phoenix Contact INTERBUS planning guide for topology-specific limits.
Q: Does the unit support PROFINET or EtherNet/IP?
A: No. The Ethernet port on the RFC 430 ETH-IB supports standard TCP/IP communication (Modbus TCP, proprietary Phoenix Contact protocols). It does not natively support PROFINET or EtherNet/IP without additional gateway hardware.
Q: What is the lead time for new stock?
A: In-stock units ship within 1–3 business days. For larger quantities or specific date-code requirements, contact us for availability confirmation.
