Enabling "Custom Macro A" for advanced programming logic.
Old Fanuc OT controls have volatile CMOS batteries. Use the PUNCH function to output all parameters to a PC: fanuc ot 900 parameter list

The on the Fanuc 0-T control are "option parameters" that enable or disable specific hardware and software features. Each parameter number (e.g., 900, 901) consists of 8 bits (labeled 0 through 7), where setting a bit to "1" activates a function and "0" deactivates it.
