25. DATA INPUT/OUTPUT
Power Mate programs, parameters, macro variables, and diagnostic
(PMC) data can be entered to or output from Series 16/18/21 through the
FANUC I/O Link.
With FANUC I/O Link, slaves in groups 0 to 15 can be connected,
enabling data input/output to and from a maximum of 16 Power Mates.
The ordinary data input/output function based on I/O Link can only be
executed in the foreground. When data input/output function B based on
I/O Link is used, the external I/O device control function is associated
with I/O Link so that an input/output group number and program number
can be specified from the PMC. The external I/O device control function
operates in the background. Therefore, when no other background
operation is being performed, data can be input/output, regardless of the
NC mode and the currently selected screen.

The programs, parameters, macro variables, and diagnostic (PMC) data
of a slave Power Mate are stored in tape format within the part program
storage length; these data items are stored as master program data in a
master program memory area.
Data input/output can be performed between the master and a slave of a
selected group. When the ordinary data input/output function based on
I/O Link is used, a group is selected by means of parameter setting. When
data input/output function B based on I/O Link is used, a group is selected
by issuing the DI signal. Data input/output cannot be performed between
the master and more than one group at a time.
