Brief Product Description

RFC430ETH‑IB, order code 2730190, is a DIN‑rail‑mounted remote field controller from Phoenix Contact RFC series. It functions as an INTERBUS master controller combining embedded PLC control, INTERBUS fieldbus master and 10/100Mbps Ethernet communication interfaces. Compliant with IEC 61131‑3 standard, it is programmed via PC WORX engineering software for distributed automation control tasks. Equipped with plug‑gable MC FLASH memory module, local digital I/O, RS‑232 service port and front‑panel diagnostic display, it bridges INTERBUS field‑level devices and upper‑level TCP/IP industrial networks. Designed for IP20 industrial cabinet installation, this legacy automation spare is supplied as fully‑tested surplus and refurbished units for maintenance and retrofit of existing INTERBUS‑based automation systems.

Core Product Functions

• INTERBUS master function, supports up to 512 fieldbus devices and large‑scale distributed I/O station management
• IEC 61131‑3 compliant PLC runtime, supports all five standard programming languages via PC WORX software
• 10/100 Mbps Ethernet RJ45 interface for TCP/IP communication, remote programming, visualization and SCADA connection
• Built‑in local digital inputs (5‑channel) and digital outputs (3‑channel) for direct on‑site signal processing
• Removable MC FLASH plug‑in memory for convenient program backup, copy and fast device replacement
• RS‑232 service interface for local commissioning, parameter download and device diagnostic access
• Front‑panel diagnostic display and LED indicators for real‑time system status, fault and bus error indication
• Integrated real‑time clock with battery backup for accurate timestamp of events and fault logs

• DIN rail mounting, wide operating temperature range for stable long‑term operation inside industrial control cabinets

Application Scenarios

• Factory automation distributed control systems based on INTERBUS fieldbus protocol
• Manufacturing production lines, material handling and conveyor system automation control cabinets
• Process industry plant control for machinery, packaging and assembly equipment
• Industrial machine control requiring mixed INTERBUS fieldbus and Ethernet TCP/IP networking
• Legacy Phoenix Contact INTERBUS automation system upgrade and on‑site expansion projects
• Spare replacement remote field controller for maintenance, troubleshooting and retrofit of existing RFC‑series control racks

FAQ (Frequently Asked Questions)

• Q: INTERBUS bus fault alarm occurs after replacing RFC430ETH‑IB (2730190)?
  A: Check INTERBUS bus cable, bus termination, field device address configuration, verify project program download and MC FLASH memory integrity.
• Q: Cannot connect to controller via Ethernet for PC WORX programming?
  A: Confirm 24VDC power supply, IP address matching, network cable status, firewall settings and correct PC WORX software version.
• Q: Can I directly copy program by swapping MC FLASH memory module?
  A: Yes, the plug‑in MC FLASH stores application program; verify hardware configuration consistency after swapping to avoid runtime errors.
• Q: Can this controller run as non‑INTERBUS standalone PLC without INTERBUS field devices?
  A: It can execute local control logic with onboard I/O, but its main strength is INTERBUS master; performance will be limited without the fieldbus network.
