2. SETTING FUNCTION
FS16i/18i/21i/0i–B PMC–SA1/SB7 MANIPULATION
853
CAUTION
Set this setting to ”NO”(0) before shipment of the machine
if you want to prohibit operator form editing the program. If
you want to protect this setting, please make a sequence
that always writes 0 in this bit by your ladder.
If you set ”HIDE PMC PARAM” to ”YES”, the following functions about
PMC parameter are protected.
– It is impossible to show Timer, Counter, Keep Relay and Data Table
screens.
– It is impossible to output PMC parameter in PMC I/O screen.
NOTE
The following operations are necessary to output PMC
parameter from I/O screen like Series 16i/18i/21i–A. The
following two methods can be used to make it possible to
output data for them.
D If the sequence program is running (RUN state) (usually,
this method should be used when the machine is
operating.)
i) Set NC to EDIT mode.
ii) The parameters are released from protection; so data
can be outputted.
D If the sequence program can be stopped (STOP state),
for example, while it is being debugged.
i) Stop the sequence program.
ii) The parameter protection is released; so data can be
outputted.
WARNING
If a sequence program is stopped while the machine is
operating, the machine may behave unexpectedly. Before
stopping the sequence program, make sure that nobody is
near the machine and that the tool cannot interfere with the
workpiece or machine. Incorrect operation of the machine
presents an extreme risk of death or serious injury to the
user. Damage the tool, workpiece, and/or the machine is
also likely.
