2 | Fanuc Focas
Originally released as FOCAS1 (Library for CNC), the evolution to represented a seismic shift. FOCAS 2 is the dynamic link library (DLL) and protocol set that allows external computers (PCs, servers, edge devices) to communicate directly with Fanuc CNCs (Series 0i, 15i, 16i, 18i, 21i, 30i, 31i, 32i, and Power Motion i) via standard Ethernet.
The answer, for the vast majority of the global manufacturing floor, lies in . fanuc focas 2
// Read Current Status (Running, Stopped, Alarm) ODBST status; ret = Focas1.cnc_rdstatus(h, out status); Console.WriteLine($"Machine State: {status.status}"); Originally released as FOCAS1 (Library for CNC), the
if (ret == 0) // Success { ODBSYS sysinfo; ret = Focas1.cnc_rdcncinfo(h, out sysinfo); Console.WriteLine($"Connected to: {sysinfo.cnc_type}"); // Read Current Status (Running, Stopped, Alarm) ODBST
If you are a manufacturing engineer, an MES developer, or an IT manager in a machine shop, understanding FOCAS 2 is no longer optional. It is the key to unlocking visibility, predictive maintenance, and autonomous operation. First, let's decode the acronym. FOCAS stands for Fanuc Open CNC API Specification .
In the race toward the "lights-out" factory and Industry 4.0, data is the new oil. For manufacturers using CNC machine tools, the single greatest bottleneck to digital transformation isn't hardware—it's communication. How do you extract real-time data from a 20-year-old machining center? How do you send a new program to 50 machines simultaneously without a USB stick?
