Graphics Object
A Graphics Object is any text, icon, or picture that can be displayed on the HMI. Graphics objects are further defined
by how they are composed or created. A Text Object is a graphics object that displays text on the HMI screen. A
Bitmap Object is a graphics object that displays a bitmap on the HMI screen. Bitmaps are files stored in the HMI to
display pictures. A Shape Object is a graphics object that displays a shape on the HMI screen. Shapes are also files
stored in the HMI to display pictures. Shapes differ from bitmaps in that shapes are stored using a vector-based file
format whereas bitmaps use a pixel-based file format. Each format has its advantages and disadvantages. For
example, vector-based graphics can be resized without losing resolution, whereas bitmap graphics lose resolution as
they are magnified. Finally, a Group Object is the most complex type of graphics object. It is a combination of other
objects. Briefly, a group object consists of one or more objects that are ‘grouped’ together and stored as one object. A
good example is a keypad, which is really a combination of several keys each designed to perform a specific task.
When grouped together, a keypad can be stored as a group object for use in other projects or windows.
Windows
A window is a screen that can be displayed on the HMI. Windows can be full-sized to completely cover the HMI
display or partially sized. Any partially sized window is usually referred to as a popup window. Windows can appear on
the HMI display by a request from the PLC or by a press from the touchscreen. Windows can be configured to any
size. Once a window is displayed, it can be moved around the HMI display or removed from the display. Windows can
even overlap each other. Each window can display graphics objects and there is no limit to the number of graphics
objects that can be placed on each window. The HMI5000P/L Series is capable of storing up to 1999 windows, but the
actual limit is determined by the total amount of memory used for the application.
What is an HMI5000P/L/HD Series?
The HMI5000P/L Series by Maple Systems are graphics operator interfaces designed to connect to PLCs in an
industrial environment. The displays are covered with analog resistive touchscreens designed for harsh industrial
environments. The touchscreens use the latest in touchscreen technology enabling the HMI programmer to create
switches that are very fine in resolution. Unlike many other touchscreen HMIs on the market, the HMI5000P/L Series
are not limited to a fixed number of cells in which switches can be created. The project can contain as many switches
of varying sizes and shapes as desired, limited only by the total amount of memory available for the project.
Three LED indicators are provided on the face of the HMI5000P Series to provide instant feedback to the HMI
operator of the current operating condition of the HMI. The HMI5000L has a power LED.
LED Indicator Purpose
PWR LED (yellow) indicates if power is applied to the OIT
CPU LED (green) indicates if the OIT is operating correctly (HMI5000P Only)
COM LED (red) indicates communications activity on PLC port (HMI5000P Only)
The HMI5000P/L Series have two serial ports, which provide a connection to a PLC using RS-232, RS-485; CANbus
communications, and an Ethernet connection for PLC communication and project upload and download. The serial
ports also provide the ability to use the EZwarePlus configuration software in Pass-Through Mode, enabling the HMI
programmer to test his project on the PLC through the HMI instead of downloading the project to the HMI.
The HMI5000HD series are DIN-rail mount units designed to display information on an HDMI video device. The
HMI5000HD units do not have an integrated display.
 The L and HD Series do not support CANbus.
