Screen Types and Templates
What is a screen?
A screen is a predefined collection of objects to be displayed at the same time. A screen is
displayed by the press of a button, function key, or can be called by a request from a PLC.
How many different types of screens are there? In MAPware-7000, you can configure or define
a screen to be one of the following:

Base Screen – this is the most common type of screen. Simply put, this is a full-sized
screen that displays objects placed onto it. The term ‘full-sized’ varies, of course,
depending upon the HMC model selected and the display size of that model. For
example, a base screen for the HMC7035A-M model (3.5” diagonal screen) is 320x240
pixels. When displayed, a base screen covers the entire area of the display.

Popup Screen – this is another common type of screen that is used to display a smaller
‘popup’ screen on top of a base screen. Popup screens allow you to display information
or objects only when needed by the HMC7000 operator. This keeps the HMC interface
more intuitive and simpler to use. Because a popup screen displays on top of a base
screen, a popup screen must be smaller than full-size for the display used.

Template Screen – This screen is also full-sized but is not called directly by a button or
function key on the HMC. It cannot display using a command from a PLC. A template
screen displays by attaching it to a base screen. When displayed, all objects on the
template screen overlay onto the base screen.

Keypad Screens – there are four pre-defined popup keypad screens: numeric keypad,
hex keypad, bit keypad, and ASCII keypad. These keypads can be used by objects (i.e. Bit
Data Entry, Numeric Data Entry) to modify register values.
Base Screens
Base screens are full-sized screens that display groups of objects (i.e. Bit Lamps, Buttons, Bar
graphs, etc.) on the HMC display.
