Custom Display
Not available in MicroLogix 1000 A.I.
Custom Display is a powerful troubleshooting tool that allows you to monitor up to 40
different data table addresses simultaneously. Addresses on the screens are shown in a
matrix of 10 rows by 4 columns. You can configure the display format for each address
independently of the other addresses (some restrictions apply for certain file types).
PLC-500 A.I. stores all the Custom Display screens for the current project in one file
with the extension .CDL. For example, if your current project is named SAMPLE,
Custom Display screens are stored in SAMPLE.CDL. This file is part of the project
and will be backed up and restored with the project.
Note With versions 8.01
α
and earlier, Custom Display screens were each stored in their own
file with a .SCR extension. These files were not a part of any particular project and as
such were not backed up with any project. You can import and export Custom Display
screens between the .SCR and .CDL formats.
The Custom Display screen operates in one of two modes, edit or monitor. Edit mode
allows you to change the screen to suit your needs. In the edit mode, each cell displays
the symbol or address for that cell. The data format is displayed directly below it. If
the cell contains a bit address the word “Bit” is displayed.
Note If your system is configured for a high resolution video mode (more than 25 lines from
top to bottom), you can access a dual screen mode which can be configured to display
between one and six lines of custom screen data at the bottom of the ladder display.
Refer to the section on Programming Screen Size in Chapter 12 - Customizing
PLC-500 A.I. for more information on video modes.
