8.2 Edit Mode
In case there is no PLC program or PLC program or parameter area is damaged in control, edit
mode is activated after turning the power on. .
Edit mode is indicated by caption EDIT in the leftmost field of the status bar. The following
actions can only be executed in edit mode:
– editing, as well as loading or saving through serial input the parameter area,
– loading PLC program to control,
– editing programs selected for execution in automatic mode and interrupted during execu-
tion, as well as editing sub-programs and macros called from this main program, on
condition that those are under processing.
If the machine is mounted with NCT machine control board the edit mode can be switched on
by pressing the button.
Editing Programs under Automatic Execution
Programs (main programs and
sub-programs under automatic
execution are indicated by excla-
mation mark ! standing before
their names on DIRECTORY
screen. These programs can be
edited with the following restric-
tions.
If automatic mode is interrupted
during execution, switch-over to
edit mode is done and the screen
EDIT is displayed, the control
always displays the currently
interrupted program, independ-
ent of the highlighted program in
the list of the directory (indicat-
ing the background editing). Editing can be done, beginning with the block after the inter-
rupted program block. The control disqualifies editing of the interrupted block and of previous
blocks. If editing of such a block is selected by means of cursor, two arrows 67, pointing at
each other indicate in the 7
th
status field, that this block cannot be edited.
The same situation occurs, if execution of a subprogram or macro is interrupted. In this case
the subprogram or macro can be modified by opening edit mode with the above restrictions.
