Determining the Presence of FOCAS in Fanuc CNC Machines

Does my Fanuc CNC have FOCAS?


How to determine if Fanuc CNC has FOCAS

Ethernet check

The best way to find out if you have FOCAS on your Fanuc i Series, is to check if you have Ethernet.


This walk through will show you how to find out, without looking in any cabinets.





Start by pressing [SYS] hard key to display the following page (if you do not see this page, press [SYS] multiple times until you do):





From this screen press the right {+} screen button until you see a screen button called {ETHPRM}, as shown below:





If you do not see {ETHPRM}, then the machine does not have Ethernet.


If you do have {ETHPRM}, press this screen button to display the available Ethernet connection. In the example above there is the standard EMBEDDED PORT and the FAST ETHERNET BOARD.


If your machine has either of these listed, then you have Ethernet. If it says PCMCIA, select {OPRT} and you might be able to change it to EMBEDDED. If you have PCMCIA, a card from FactoryWiz can be used to collect data.


Note: Different versions of Fanuc controls have slight variations on the term ETHPRM, some have ETH PARAM / ETHER / etc.


Does not have Ethernet or Focas

Could have Ethernet

Has Ethernet as standard

O Series

0i-B (with PCMCIA)

0i-D/F

3 / 6 Series

0i-C

16i / 18i B

16 / 15 / 18 / 21 (non i)

21i-B

30i Series

15i-A/B



16i / 18i / 21i A*




* It is possible to have ethernet on 16i / 18i A series controls. This was an option from Fanuc. We estimate only 10% of these controls have ethernet. It is normally only on more high end machinery.
