Product Overview

The Fanuc Focas HSSB device driver exchanges data between OPC clients and Focas CNCs. Kepware automatically optimizes your data acquisition based on client demand. Data integrity is ensured with our extensive error handling.

This driver requires that FANUC CNC Focas1/Ethernet Library or FANUC Focas2 Library be installed on the system in order to communicate with the hardware. The library does not need to be installed to create a server project, but the project will not run without it.
