: FOCAS API functions return specific error codes that must be checked after each call. Common errors include connection timeouts, permission issues, and invalid parameter values. Implement retry logic with exponential backoff for transient network failures.
FANUC FOCAS 2 is a specialized Application Programming Interface (API) developed by FANUC. It acts as a digital bridge, allowing external software applications to communicate directly with FANUC CNC controls and Power Mate controllers over an Ethernet (TCP/IP) or PCMCIA HSSB (High-Speed Serial Bus) connection.
(Fanuc Open CNC API Specifications) is a powerful communication protocol and library that bridges the gap between FANUC CNC controllers and external PC applications. It allows developers to "ask" a machine for real-time data or issue commands, making it a cornerstone of modern smart manufacturing and Industrial IoT (IIoT). Core Capabilities
FOCAS2 is the engine that drives countless IIoT applications in modern smart factories. Its ability to provide millisecond-level data directly from the CNC kernel opens up a world of possibilities. fanuc focas 2
FOCAS 2 is the foundational technology for virtually every Manufacturing Execution System (MES), IIoT platform, and predictive maintenance tool in a FANUC-based shop.
By logging spindle power, temperature, and motor currents, operators can detect anomalies before they cause a machine failure.
FOCAS2 is the clear choice for any new integration. It is faster to deploy, easier to maintain, more scalable, and future-proof for modern FANUC CNCs. You should only consider FOCAS1 if you are dealing with legacy controls that cannot be retrofitted with Ethernet. : FOCAS API functions return specific error codes
To build a FOCAS-based application, you generally need the following components:
: Avoid frequent small data requests; where possible, use bulk read operations to retrieve multiple data points in a single call. Adjust polling frequency based on actual monitoring requirements rather than defaulting to unnecessarily high rates that waste network bandwidth and CNC processing resources.
Do not confuse the CNC option cost with third-party commercial software. The option fee is paid directly to FANUC or your machine tool builder to enable the capability on the controller itself. FANUC FOCAS 2 is a specialized Application Programming
A specialized, ultra-fast fiber-optic connection for high-performance data exchange. Why Use It? Modern manufacturing is all about data. By using the FOCAS2 Library , you can build custom applications to: Monitor Performance: Track part counts, cycle times, and idle status. Manage Programs:
Read and write to PMC addresses (Inputs, Outputs, Registers, Timers, Counters). This allows external software to interact directly with peripheral hardware like robotic loaders, bar feeders, and safety enclosures. How FOCAS 2 Drives Smart Manufacturing
