High-performance connectivity for Focas Ethernet CNC systems
This driver is only available as part of the following TOP Server driver suites:
Channels (20 Devices Each)
Focas Libraries (1 & 2)
CNC Series Supported
Fast Ethernet Data Mode
The Fanuc Focas Ethernet Driver works in conjunction with TOP Server® to provide data exchange between OPC UA, OPC DA, SuiteLink and DDE clients and Computer Numerical Control (CNC) systems using the Fanuc Focas Ethernet protocol. This driver supports polling but also the unsolicited communications mode of the Fast Ethernet card in the CNCs. Data acquisition is optimized based on upstream client demand while data integrity is ensured using extensive error handling.
Note: This driver uses and requires either the Focas 1 or the Focas 2 interface libraries that are available from FANUC America Corporation. (The Focas2 Library combines both Ethernet and HSSB capabilities.) Although it is not required that the library is installed in order to create a server project, the project will not run without it. This software may be obtained from a FANUC distributor, or by calling 1-888-FANUC-US (1-888-326-8287).
Proven benefits for Fanuc CNC Ethernet connectivity
Monitor CNC status and performance in real-time via Ethernet
Collect data for OEE calculation and production optimization
Access alarm information with type and details via cnc_rdalmmsg
Read complete program directory from CNC via cnc_rdprogdir3
Event-driven updates via Fast Ethernet card for real-time responsiveness
Ideal for MES, production monitoring, OEE, and predictive maintenance initiatives
"The Software Toolbox support team was very helpful and provided lots of useful advice and links to help me solve my issue."
