Simple geometric shapes can be drawn on a Display.
Graphic images can be imported from the Image Library, or created with a program such as Microsoft Paint and then imported.
Fixed graphic images
This type of image stays on the screen and does not change until a different Display is loaded by the program.
Variable graphic images
Variable images change according to the value of a linked operand. Binary Image Variables are linked to bit operand status (MB, SB, I, T, O). List Image Variables are linked to integers (MI, SI, ML, SL)
You can draw graphic images directly on a Display, or import images.

Although an imported image can be resized, resizing may result in some degree of distortion. To avoid this, use images that are created to match the required size. |

The HMI display uses a grid which spaces the lines 8 pixels apart. To optimize Displays and shorten the PLC cycle time, images and variables should be aligned to grid.
