❌ You need quick setup, modern security, or cannot get the FOCAS option enabled on your machines. Consider MTConnect or an external PLC‑based data collection for simpler read‑only needs.
FANUC FOCAS 2 (FANUC Open Architecture and Communications) is a software library developed by FANUC to facilitate communication between its CNC machines and external devices such as computers, PLCs, and other machines. FOCAS 2 is an extension of the original FOCAS library, offering enhanced functionality, improved performance, and increased reliability.
Researchers use FOCAS 2 to collect command and feedback positions at high frequencies, feeding this data into deep learning models (like LSTM networks
FOCAS 2 runs over the standard Ethernet port available on most modern FANUC CNCs. Implementing FOCAS 2 in Your Factory fanuc focas 2
FOCAS 2 is often a required option (software package) that must be enabled on the FANUC CNC itself.
Call specific functions like cnc_statinfo (for machine state) or cnc_rdposition (for axis coordinates).
FOCAS2 uses a standard over TCP/IP Ethernet . Here’s how it works: ❌ You need quick setup, modern security, or
In the era of Industry 4.0, the ability to collect, analyze, and act on data from the shop floor is no longer a luxury—it is a necessity. FANUC, a global leader in CNC systems, robotics, and factory automation, provides the tools to unlock this potential through its proprietary communication protocol: (Fanuc Open CNC API Specifications).
FOCAS 2 can read macro variables or part counters directly from the CNC memory. This provides production managers with real-time updates on job completion percentages and accurate cycle time benchmarks for quoting future work. 4. Smart Factory Integration (MES & ERP)
A key advantage in many modern implementations is that FOCAS2 enables this connectivity . This makes it a low-risk, high-reward solution for brownfield sites where reprogramming every machine is not feasible. FOCAS 2 is an extension of the original
The machine must be connected to the factory network via Ethernet, requiring IP address configuration within the CNC settings. 2. Software Development (API)
The versatility of FOCAS2 enables a wide range of practical applications that deliver measurable business value.
By logging spindle load, axis temperature, and servo currents via FOCAS 2, data scientists can build predictive models. A sudden spike in spindle load during a specific cutting cycle can flag a dull tool or failing bearing before a catastrophic breakage occurs. Automated Part Tracking and Quality Control
High-frequency data polling can create heavy network traffic. It is critical to isolate CNC networks from general corporate IT traffic using VLANs to prevent latency issues.
