Appendix 6 Creating Scale Images
Scale Images
In addition to the standard scale, you can display original scales that you create. You can
display scale images at the display group level.
This feature is useful when you want to use your own scale or need a special scale for
nonlinear input signals or other nonstandard signals.
Creating a Scale Image
You can create a scale image based on a GX/GP trend screen that has been configured
appropriately for your purpose. Using the GX/GP snapshot feature, save an image data
(PNG format) of the trend screen to the SD memory card. Edit the image data using a
software application that can handle PNG files (Windows Paint for example) to create the
scale image.
Scale Image Creation Workflow
1
Configuring the trend screen settings
Set the trend screen’s display direction, scale position, and the position of digital values.
2
Displaying the trend screen and capturing image data
On the GX/GP, display the group trend screen that you want to show the scale image in. Using
the snapshot feature, save an image data of the trend screen to the SD memory card.
3
Creating the scale image
Create the scale image by editing the image data on an image editing software application.
