FOCAS 2 eliminates the need for guesswork. It provides a direct line to the CNC’s internal memory.
Understanding FANUC FOCAS 2: The Gateway to CNC Automation and Data Extraction
Modern manufacturing execution systems (MES) leverage FOCAS 2 to create live 3D representations or dashboards of the shop floor. Management can see precise part counts, cycle times, and machine statuses updated in sub-second intervals from anywhere in the world. Automated Part Traceability
If you are in manufacturing, waiting for "native IoT" on your 10-year-old Fanuc is a losing strategy. is the proven, reliable workhorse that powers the majority of today's industrial IoT platforms (like MachineMetrics, FreePoint, and MES systems). fanuc focas 2
The Fanuc unit (Series 16i/18i/21i, 30i/31i/32i, Power Mate, etc.) acts as the data source.
Before the widespread adoption of APIs like FOCAS 2, collecting data from a CNC mill or lathe was a game of workarounds. Companies often relied on macro variables or clunky hardware sensors attached to the outside of the machine to detect if the spindle was running.
FOCAS, which stands for , is a specialized software interface. It enables external applications to communicate directly with FANUC CNC controllers over an Ethernet or PCMCIA network. FOCAS 2 is the modern, extended version of the original FOCAS interface, offering expanded function libraries to handle complex data extraction for modern machining. FOCAS 2 eliminates the need for guesswork
Pushing new CNC programs directly from the office engineering server to the machine without manual USB handling. Setup and Requirements for FOCAS 2
Using cnc_rdspindleload() , a monitoring system tracks the spindle load on a roughing operation. Over 100 parts, the baseline load is 45%. When the load rises to 62% (indicating a worn insert), the software flags the machine for maintenance before the tool breaks and scraps the part.
: Developers can use these libraries to read and write a vast range of CNC and PMC data, including: Tool offsets, part counts, and cycle times. Alarm messages and event logs. Management can see precise part counts, cycle times,
The true value of FOCAS2 lies in the vast amount of data it can unlock. With the appropriate licensing enabled on the CNC, you can both read and write data across dozens of categories. According to official FANUC documentation, the library provides functions to access:
using Fwlib; // Reference to FOCAS DLL
// Connect to CNC at 192.168.1.100 short ret = Focas1.cnc_allclibhndl3("192.168.1.100", 8193, 1, out ushort h);
Development libraries are typically provided by Fanuc to application developers to build the monitoring software. Conclusion
