NOTE
1 When [PMCLAD] soft key is pressed, the screen which was
displayed last time among Ladder Diagram Monitor screen,
Collective Monitor screen, Step Sequence Monitor screen,
and Program List Viewer screen is displayed. When
[PMCLAD] soft key is pressed at first time after CNC power
is on, Program List Viewer screen is displayed. Changing
the ladder program by I/O function will also make Program
List Viewer screen appears at [PMCLAD] soft key again.
See ”Program List Viewer screen” for more detail.
2 [EDIT] soft key in Ladder Diagram Monitor screen appears
only when Programmer function is enabled. To enable
Programmer function, set ”PROGRAMMER ENABLE” to
”YES” at GENERAL screen of PMC Settings or set keep
relay K900.1 to 1. Or, set ”EDIT ENABLE” to ”YES” or set
K901.6 to 1. While Online Monitor function is active, you can
not reach Ladder Diagram Editor screen. To use Ladder
Diagram Editor function, you have to disable Online Monitor
function at ”RS–232C” and ”F–BUS” on ”PARAMETERS
FOR ONLINE MONITOR”: choose ”NOT USE”.
3 Refer to ”7.2 DISPLAYING RUN STATUS ” for the Step
Sequence State screen in the figure.
The subprogram of step sequence can farther more call other subprogram
of step sequence. (So, called ”nesting of the block”) Therefore, you must
think about the level of nested hierarchy of a current subprogram when
you think about the movement of the screen of step sequence program. As
for this hierarchy, a Subprogram List Viewer screen is the top. As nest of
the subprogram becomes deeper, the hierarchy falls down.
There are three screen which displays information on the subprogram of
step sequence. The Step Sequence Monitor screen, the Step Sequence
State screen, the Sub Program List Viewer screen. These three screens can
display the various information of the same subprogram by changing
display by the [STEP], [SPLIST], [STATE] soft keys. These soft key will
switch these screens in the same level of the program hierarchy.
Contrary to this, the screen moves to the Step Sequence Monitor screen
at one deeper level in the hierarchy when the cursor is put on a step
sequence and [ZOOM]soft key is pushed on the Step Sequence Monitor
screen or the Subprogram List Viewer screen. When [BACK] soft key is
pushed, it is returned to Step Sequence Monitor screen of the hierarchy
(= one level upper in the hierarchy ) of the subprogram is called.
