Projects
The HMC7000 has two basic segments of internal memory. The code memory (firmware)
contains the information required by the HMC that controls how it operates such as the features
supported and how it communicates to a third party PLC. The HMC programmer does not have
the ability to change this code memory. Project memory pertains to all the window screens,
ladder logic created, and any other features that the HMC programmer can create using the
MAPware-7000 configuration software. Therefore, the term project designates the file sent to
the HMC7000 from the MAPware-7000 software.
Backing Up Projects
The MAPware-7000 configuration software does not perform automatic saving of the open
project. We recommend that you frequently save your project as you are working on it to make
sure that no work is needlessly lost in the event of a power failure or computer error. When
you have completed a project, we strongly urge that you archive it to another folder, an external
network drive, or storage media for safekeeping. Although Maple Systems does provide repair
support on all of our products, we cannot guarantee that we will be able to restore a project on
a damaged unit.
Objects
An object is any ‘thing’ that performs an action while the HMC is communicating to the PLC. In
order to get the HMC to ‘do anything’, you must program the HMC with objects. Objects
perform actions such as display text or graphics, write a value to a PLC register, control an I/O
expansion module, or display an alarm. Objects most often are graphics shapes that display on
the HMC screen. For example, a text object displays text on the HMC. However, objects are
also used to configure the HMC7000 to perform some action. For example, a Numeric Data
Display object tells the HMC7000 to continuously monitor a PLC register and display the number
in that register. Some objects can display a graphics shape on the HMC7000 screen and perform
some action. A Toggle Bit Object creates a graphic object on the HMC7000 that, when pressed,
activates a bit in the PLC.
Graphics Objects
A Graphics Object is any text, icon, or picture that displays on the HMC7000. Graphics objects
are further defined by how they are composed or created. A Text Object is a graphics object
that displays text on the HMC screen. A Picture Object is a graphics object that displays a
bitmap or JPG on the HMC screen. Most of the objects available in the MAPware-7000 software
can display a predefined shape, picture, or text.
Windows
A window is a pre-programmed screen of objects that displays on the HMC7000. Windows can
be full-sized (meaning that when displayed they completely cover the HMC7000 display), or a
window can be partially sized (the window is ‘overlaid’ on top of a full-sized window). Partially
sized windows are also known as ‘popup windows’. Windows appear on the HMC7000 display
by a request from the PLC or by a press from the touchscreen (or function keys). Once a
