Product Description:

The E4809-045-223-A is a control board manufactured by Okuma for the E4809 CNC Boards series. Installed in machining centers that run on the OSP-U100 architecture, the board functions as the central Fieldnet node that ties numerical control logic to remote drives, sensors, and human-machine interfaces. By assuming the master position on the plant’s fiber network, it streamlines signal distribution for axis positioning, tool measurement, and programmable logic tasks in automated production lines.

This model is identified as a Fieldnet Control Processor, which indicates onboard resources for deterministic network scheduling and data buffering. It is designed specifically for the OSP-U100 control platform, so protocol timing, memory mapping, and diagnostics align directly with Okuma’s software kernel. The fiber channel uses a single-core strand in each transmit-receive pair to keep installation simple while preserving optical isolation. Physical connection is achieved through the compact XB-RT plug, which provides a secure optical interface without requiring fiber polishing during installation. All process traffic travels over a Fiber Optic medium, which eliminates electrical noise coupling from spindle drives and welders that share the same cabinet.

An individual link handled by the processor can supervise up to 8 motion axes, so multi-axis lathes or machining centers can run on one optical ring. Four dedicated ports accept probing devices, and the board counts these as 4 sensor channels for automatic part touch-off. Each channel supports Touchsetters, enabling closed-loop tool length compensation without external converters. The board appears on both the I/O and servo rings as a Master Station, which lets it issue synchronous position frames while simultaneously polling distributed PLC I/O on one deterministic schedule.
