How Do I Know if My Control Interface Supports FOCAS?

Determining whether your control interface will support FANUC FOCAS involves checking the type of CNC and the Series version you have.

Here’s a general guide:

• FOCAS is available on FANUC Series 30i/31i/32i/35i, 31i-Model B, 32i-Model B, and Power Mate i.
• For the older series such as 0i, 16i, 18i, 21i, 0i-D, and 0i-F, FOCAS might be available but it would be best to check with your FANUC representative or machine tool builder.
• If your CNC is equipped with Ethernet, there is a high probability that it supports FOCAS.

However, please note that even if your CNC is one of the above types, it might not support FOCAS due to customization by the machine tool builder. Therefore, it’s always advisable to contact your local FANUC representative or machine tool supplier for confirmation.

Also, keep in mind that if FOCAS is not currently enabled on your control, it can usually be added by purchasing and installing an option from FANUC.
