Fanuc Focas 2 !!install!! Review
Many manufacturers ask whether they should use FOCAS 2 or MTConnect.
Implementing FANUC FOCAS 2 requires a thorough understanding of the interface specification and its protocols. Here are some steps to follow:
FOCAS 2 provides comprehensive access to hundreds of internal parameters and status points within the FANUC controller. The accessible data generally falls into five main categories: 1. Axis and Position Data
Use specific API calls like cnc_statinfo() for machine state or cnc_rdsrvspeed() for motor speeds. fanuc focas 2
Access tool life data, tool offsets, and change information.
// Allocate library handle ret = cnc_allclibhndl3(ip_address, port, timeout, &h);
If the Ethernet board option is missing or inactive, contact your machine builder, dealer, or FANUC support to enable it. Expect activation fees typically ranging from $500 to $2,000 per machine. Many manufacturers ask whether they should use FOCAS
FANUC FOCAS is a set of library files (DLLs) that act as a translator. While FOCAS 1 was the standard for older CNC models,
An enabled Ethernet port on the FANUC Data Server or the "Embedded Ethernet" port.
A central server polls 100+ CNCs every 2 seconds for: The accessible data generally falls into five main
: While the older FOCAS 1 targeted legacy series (like 16i, 18i, 21i), FOCAS 2 supports modern, Ethernet-capable families such as the 0i-F/0i-MF and the advanced 30i/31i/32i Comprehensive Data Access
Displaying real-time machine uptime, efficiency (OEE), and production part counts on large screens for operator visibility.
This SDK includes dynamic link libraries (like fwlib32.dll for 32-bit or fwlib64.dll for 64-bit systems), header files, and documentation. By integrating these into your own software, you can programmatically read any data from the CNC and even write commands or data back to it.
In conclusion, FANUC FOCAS 2 is a powerful interface specification that has transformed the industrial automation landscape. Its open, flexible, and scalable nature makes it an ideal solution for a wide range of applications, and its future developments are expected to shape the evolution of Industry 4.0 and the IIoT.
Unlike basic I/O monitoring, FOCAS 2 allows for granular data extraction, such as internal axis loads and detailed spindle data at high frequencies (up to 70 Hz for certain data points).
