Eliminates manual data entry by pulling production counts directly from the controller.

| Feature | FOCAS 2 | MTConnect (FANUC) | Manual B‑register reading | |----------------------------------|----------------------------|---------------------------|----------------------------| | | Very high (10–100 ms) | Low–medium (500 ms+) | Slow, operator‑dependent | | Write to CNC | Yes (programs, variables) | Typically no | No | | Setup complexity | High (library + network) | Medium (agent config) | Low (but manual) | | Requires CNC option license | Yes (FOCAS enabled) | Sometimes also requires it | No | | Security | None (plaintext) | Basic (HTTP) | N/A |

The FOCAS 2 library provides a set of APIs (Application Programming Interfaces) that allow developers to create custom applications, enabling the exchange of data between FANUC CNC machines and external devices. This enables users to integrate their FANUC machines with other systems, creating a more streamlined and efficient production environment.

FANUC FOCAS2 (FANUC Open CNC API Specifications) is a set of library files (DLLs) designed for developers to create custom Windows applications that communicate directly with FANUC CNCs via Ethernet or High-Speed Sub-Board (HSSB)
