Push Buttons

Publication 2711E-820 – January 1998

Important:

In Remote I/O applications, 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, don’t
use a Multistate Push Button to initiate a
PLC-controlled machine or process. Use a Momentary
Push Button instead.

Configuring the Multistate Push Button

Configure the Multistate 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 Multistate Push Button.

Function Key
(Keypad only)

Specify which function key the operator must press to activate
this button.

Number of States

Assign from 2 to 255 states to the button. If you increase the
number of states from the default of 2, you must assign state
values. To do so, choose Edit States, described below.

Initial State

You can assign any state to be the button’s initial state. This
state’s value is written to the Button Control when the
application runs for the first time. This value overrides the
control’s initial value.

You don’t 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 writes the tag’s initial value to the Button Control.

Edit States

If you wish, you can edit the values of each state. For example,
if you assign three states, you could assign 100 to state 0, 200
to state 1, and 57 to state 3.

To assign different values to the states, choose Edit States.
Assign a unique value from –2,147,483,648 to 2,147,483,647
for each state. See “Configuring Object States” in Chapter 9,
Creating Objects, in the PanelBuilder 1400e Configuration
Software for Windows User Manual
for more information.

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.

Auto-Repeat Rate

Specify how many times the button will repeat per second, if
held down. A value of 0 disables auto-repeat.

Auto-Repeat Start
Delay

Specify how long the button must be held down before it starts
to auto-repeat.
