13. INPUT/OUTPUT OF DATA
815
The data input/output function based on the FANUC I/O Link is
implemented by various elements such as ladder programs, I/O Link
assignment, Series 0i/0i Mate parameters, and power mate CNC
parameters. So, problems may occur when the function is started.
The table below lists the symptoms of the problems that may occur,
together with their causes and corresponding corrective actions.
Symptom Cause and corrective action
Data input/output is started, but the
Series 0i/0i Mate and power mate
CNC return no response.
The background is already active (the
background busy signal BGEACT is
set to 1). In this case, the function
cannot be used.
Examples:
1) In MDI mode, the program screen
is selected.
2) Background editing has already
started.
Communication via the RS–232–C
interface is in progress.
Multiple communication operations
cannot be performed at the same
time, such that any subsequent at-
tempt to start the function is ignored.
The selected slave is not a power
mate CNC.
Data input/output function B based on
the I/O Link is not started if the slave
specified with a group number set
with group number specification sig-
nals SRLNI0 to SRLNI3 is other than
a power mate CNC.
A ladder program error may prevent
the function from being started.
Check the ladder program for errors
such as mis–specified addresses.
When an attempt is made to output
data to a power mate CNC:
