Controller diagnostics

Use the controller diagnostics page to compare the configuration settings between the current project and the connected controller. If the controller is disconnected when viewing the controller diagnostics page, the page will become not available.
The controller diagnostics page contains the following sections:
  • Controller Identity
  • Startup
  • Memory Module or Memory Card
  • Controller Information
    (L20E, L50E, and L70E controllers)
  • Summary
When the memory module, memory card, or LCD module is unavailable, unplugged, or corrupted, their values are
Not available
. The
Summary
 section indicates their non-availability.
The controller diagnostics page does not differentiate between memory module, memory card, and LCD module for different controller families.
