Disable Individual Categories of Messages

You can disable a subset of the information that scrolls across the controller 4-character display. You can disable these subsets:
  • Project name and link status
  • Port status and IP address
Complete these steps.
  1. Add an MSG instruction to your program. This message only has to execute once, it does not need to execute with every program scan.
    IMPORTANT:
    You cannot add an MSG instruction to your program if the controller switch is in Run mode, or if the
    FactoryTalk® Security
     settings deny this editing option.
  2. Configure the Configuration table on the Message Configuration dialog box as described in the table below.
    This image shows how to configure an MSG instruction to disable individual categories in Logix Designer.

    To re-enable the subsets, complete the steps that are described in this section. Before you enable the MSG instructions, be sure that the appropriate bit in the Source Element tag value is 0.
