110 Push Buttons
Publication 2711E-6.15 – November 1998
Field Meaning
Control The Multistate Push Button uses the following controls:
Button Control records the status of the button. You can
assign only a tag to this control.
When the application runs for the first time, the value of the
initial state is written to the Button Control. Each time the button
is pressed, the value of the next state is sent to the Button
Control. After the value for the last state is sent, the next button
press wraps back to the first state.
The button recognizes external control value changes. If the
Button Control value changes to one that does not match any of
the state values, the next button pressed sets the button to
state 0.
Note: If you do not assign this control, an error state occurs
when the object is displayed on the PanelView terminal. The
highest state is displayed without its label, alerting the operator
to the error state.
Indicator State controls the display state of the object. You can
assign a tag or expression to this control.
If you assign just the Button Control and not the Indicator State
control, the button state is displayed as soon as the button is
pressed and released. In this case, the feedback for this control
is local and immediate. It does not necessarily reflect the Button
Control’s value.
You can assign the same tag to the Button Control and Indicator
State control. In this case, the terminal displays the button state
based on the Button Control value. This is a more reliable way
of configuring the button; however, if traffic is heavy over DH+ or
ControlNet, the display response may be delayed.
You can provide a visual handshake with the PLC by assigning
different PLC addresses to the Button Control and Indicator
State control. If the PLC is programmed to match the value of
the Indicator State control to the value of the Button Control, the
button changes to the state with that value.
If the Indicator State control value does not match any of the
state values, an error state occurs and the button displays the
highest state without its label.
You can adjust the size of the object and format its foreground color,
background color, button margins (touch screen applications only),
border style, fill style, and blink attributes. For details on formatting
objects see “Changing Object Appearance” in Chapter 9, Creating
Objects, in the PanelBuilder 1400e Configuration Software for
Windows User Manual.
