60 Numerics
Publication 2711E-6.15 – November 1998
Note: When the button is released, the Numeric Display component
will recognize any external changes to the Button Control and update
itself.
At runtime, if the numeric value cannot be displayed—for example,
if the field is too small—the Numeric Display component is filled
with asterisks (***).
Important: For Remote I/O applications, and ControlNet
Unscheduled tags, the PanelView terminal can retain
the current Button Control value, even after the terminal
is turned off. Depending on how the Application
Startup operation is defined, the retained value (last
state) or initial value (default) is sent to the PLC when
power is reapplied.
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.
!
ATTENTION: A control function should require
operator confirmation. Do not use this object on its
own to initiate a control function. Also, a retained
value could be used when the terminal is powered back
on, which could result in a control function starting
without the operator’s knowledge.
