Push Buttons

Publication 2711E-6.15 – November 1998

The Multistate Push Button enables the operator to send a
pre-configured series of values to the PLC.

Each button state can be configured with different attributes such as
text and graphic image labels and colors.

At runtime, if the Button Control cannot accommodate the state
value (if the value is too large for the control’s address), an error
message is displayed, and the PLC value is not changed. The
operator must clear the fault before continuing.

Note: If the Indicator State value does not match any of the defined
state values, an error state occurs and the button displays the highest
state without labels. An error state also occurs if the Button Control
is not assigned. In this case also, the button displays the highest state
without labels.

Important:

For Remote I/O applications, and ControlNet Scheduled
tags, depending on how the Application Startup screen
is configured, the terminal can retain the current value
for the button setting even after the terminal is turned
off. For this reason, do not use a Multistate Push Button
to initiate a PLC-controlled machine or process.
Instead, use a Momentary Push Button.

For DH+ applications, ControlNet Unscheduled tags,
and Modbus applications, the current value cannot be
retained. Depending on how the Application Startup
operation is defined, the initial value or nothing
(default) is sent to the PLC when power is applied.

For details on configuring Application Startup
operation, see “Application Startup” in Chapter 5 of the
PanelView 1000e, 1200e, and 1400e Operator
Terminals User Manual.
