Product Highlights

PROFINET IRT — 1 ms Cycle Time

Isochronous Real Time support for deterministic motion control. Cycle times down to 1 ms for precise multi-axis drive synchronisation.

64 Modules / 1024 I/O Channels

Connect up to 64 u-remote I/O modules per coupler station — a mix of digital, analog, and technology modules.

Mixed IP20 / IP67 Architecture

Cabinet-mount IP20 and field-side IP67 modules in one unified u-remote architecture — no additional gateway required.

Hot-Swap Module Replacement

Replace I/O modules during operation without stopping the PLC cycle, minimising production downtime.

Integrated Channel-Level Diagnostics

Comprehensive diagnostics via PROFINET and LED indicators — faster fault finding at the source.

u-mation Ecosystem Ready

Native integration with u-OS edge computing and the easyConnect Industrial Service Platform.

Product Description

The UR20-FBC-PN-IRT-V2 is a modular PROFINET IRT fieldbus coupler for the u-remote I/O system. It enables high-precision, deterministic communication at cycle times down to 1 ms — suitable for motion control and time-sensitive automation tasks.

With support for up to 64 I/O modules per station, the UR20-FBC-PN-IRT-V2 offers maximum flexibility in cabinet construction. Hot-swap module replacement allows maintenance without shutting down the station. The system supports mixed IP20 and IP67 installations within a single bus structure.

The coupler is fully compatible with the u-mation software ecosystem including the u-remote Configuration Tool and Siemens TIA Portal integration.

What is the minimum PROFINET cycle time? +
The UR20-FBC-PN-IRT-V2 supports IRT cycle times down to 1 ms for high-speed motion control and synchronised drive applications.
How many I/O modules per coupler? +
Up to 64 u-remote I/O modules — providing up to 1,024 digital channels or a mix of digital and analog I/O.
Can I mix IP20 and IP67 modules? +
Yes. IP20 modules mount on the DIN rail; IP67 field modules connect via bus cables from the same coupler in a single u-remote station.
Is hot-swap replacement supported? +
Yes. All u-remote I/O modules support hot-swap while the coupler remains powered and the PLC scan continues.
Which PLCs are compatible? +
All PROFINET-capable controllers: Siemens S7/TIA Portal, Beckhoff TwinCAT, ABB, Rockwell, Schneider. GSDML file available for download.
