Push Buttons
All push buttons cause some action to be performed when pressed (or released
in some cases). They come in a variety of different shapes and colours. In
addition they come in a variety of categories, where each category performs
a different type of action.
Push Button Shapes
Push buttons shapes come in the following shapes and sizes. Most buttons
are available in multiple different shapes, and the images associated with
the descriptions are examples only.

Menu Push Buttons
A menu push button selects an SVG layer for display. This does not write
data to the HMI server, but rather it just affects what is displayed on the
HMI screen.

Increment/Decrement Push Buttons
Increment and decrement push button increment or decrement a value in the
HMI server with respect to a reference value. Typically, the tag (address) of
this reference value will be the same as the target address. However, it may
be different address if that is required.

integer
|
Any valid integer
|
The amount to increment by each time the button is clicked
|
| Limit
|
integer
|
Any valid integer
|
The maximum limit for incrementing
|
Note: For a decrement button, the increment value
should be negative. This will be added to the current
value, so you want to add a negative number (which will result in a
subraction). The limit should also be negative.
When the limit value is reached, the button will no longer increment the
value.
Write Integer, Float or String Push Buttons
Write integer, float, or string push buttons will write an integer, float,
or string constant to the HMI server when pressed. The write integer push
button differs from the constant 0 and constant 1 push buttons in that the
integer to be written is a parameter rather than a fixed value.

Momentary Push Buttons
Momentary push buttons write a 1 to the HMI server when pressed, and then
a 0 when released. This means the value will only be turned on so long as the
button is pressed.

Pulse Push Buttons
A pulse push buttons writes a 1 to the HMI server when pressed, followed
by a 0 after a time delay. This differs from a momentary button in that the
time between writing a 1 and a zero is predictable and regular.

| Pulse Length (msec)

Note: The pulse length parameter is the time in
milliseconds between the button being activated and the zero value being
written.
Toggle Push Buttons
A toggle push buttons uses a reference address (tag) to decide what to
write when activated. If the reference value is 0, it writes a 1 to the HMI
server. If the reference value is not 0, it writes a zero. This causes it to
toggle between 0 and 1.
Toggle push buttons that do not use a separate reference tag use the
input tag as the reference value. Buttons that allow the use of a
separate reference tag (address) would normally use a different tag for this,
but may use the same tag for both parameters if desired.

Illuminated Push Buttons
Illuminated push buttons combine the functions of pilot lights and push
buttons. The push button component works the same way as the corresponding
conventional push button. The button colour is controlled in the same manner
as a pilot light.
