106 Push Buttons
Publication 2711E-6.15 – November 1998
Important: For Remote I/O applications, and ControlNet Scheduled
tags, depending on how the Application Startup screen
is configured, the PanelView terminal can retain the
current value for the button setting even after the
terminal is turned off. For this reason, do not use a
Maintained Push Button to initiate a PLC-controlled
machine or process. Instead, use a Latched or
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.
Configuring the Maintained Push Button
Configure the Maintained Push Button according to the following
table:
Field Meaning
Name Assign a name, up to 15 characters to document the object for
printed reports. This increases the application’s size by 1 byte
per character.
Button Type Specify a Maintained Push Button.
Function Key
(Keypad only) Specify which function key the operator must press to activate
this button.
Number of States Only two states are possible. You cannot change this number.
Initial State You can assign either state to be the button’s initial state. This
state’s value will be written to the Button Control when the
application is run for the first time. This value will override the
control’s initial value.
You do not need to assign any state as the initial state. You can
instead assign the button’s initial state to be blank. If you do, the
object will write the tag’s initial value to the Button Control.
Edit States If you wish, you can edit the values of each state. For example,
you could assign 100 to state 0, and 200 to state 1.
To change the state values, choose Edit States. You can assign
any unique value from –2,147,483,648 to 2,147,483,647. For
more information, see “Configuring Object States” in Chapter 9,
Creating Objects, in the PanelBuilder 1400e Configuration
Software for Windows User Manual.
Note: To minimize the size of the application file, use state
values that increment by one for each state. Do not configure
more states than you need.
