Button Control
This control consists of a lamp section whose light section color and
caption change according to the state of an input signal from the PMC,
and a switch section that performs the following operations when the
button section is pressed:
<1> Setting of bits in the PMC area
<2> Writing of fixed data to the PMC area
<3> Calling of an FP function
<4> Calling of a screen (used with momentary type)
<5> Switching of history message indication control screens
The state of output to the PMC area is preserved after the screen is
switched.
Two switch types are available: momentary type and alternate type.
This button can be interlocked when functioning as a push button.
When the embedded-plug indication is selected, this control can be set
not to function as a button.
In addition to the normal on/off-style indication the following three
types of button style indications are supported: (normal indication),
embedded-plug-style indication, embedded-plug-style indication by an
invalid signal, and interlocking-style indication.
(1) Embedded-plug-style indication
This indication displays the control as an embedded plug from
the time of screen layout design. To switch to a button, change
the property. This indication requires much less built-in memory
in the CNC than the embedded-plug-style indication by an
invalid signal. This embedded-plug-style indication cannot be
used with either of the following indications described in items
(2) and (3).
This embedded plug style is specified in [Property] on the
[Image] tab.
(2) Embedded-plug-style indication by an invalid signal
When the invalid signal specified during power-up is turned on,
the embedded-plug-style indication is used. The state of the
invalid signal is obtained during power-up. Therefore, even if the
state is changed by the PMC after this process has started, the
style indication for the button is not affected. For the button with
the invalid signal set to OFF, the normal button operation and the
button style indication during input of the interlock signal
described in item (3) can be used. Unlike the
embedded-plug-style indication described in item (1), the
indication type on the CNC screen can be determined by the
signal state during power-up without changing the property.
This embedded plug style is specified in [Property] on the
[NoAction Image] tab.
