Many Fanuc "i" series controls have Fanuc FOCAS support, which will integrate seamlessly with MachineMetrics. To check if your control supports Fanuc FOCAS, try the following:
On the machine control, press the system hardkey, then the scroll using the right arrow softkey until you see the menu option (ETHPRM).
If you do not see a ETHPRM option your machine does not have FOCAS equipped.
If you do see ETHPRM, select it. Look for an option called either "EMBDD" or "EMBED", and hit select.
On some controls you may see an option for "FOCAS 2" if not, press the down arrow softkey until you see "FOCAS" options displayed. If you do not see either of these, then unfortunately your machine control is not capable of FOCAS data.
