Disable the Controller Memory Card

With the
Studio 5000 Logix Designer®
 application, you can use a
CIP™
 Generic MSG with a Path of THIS to execute this option.
IMPORTANT:
Remember the following:
  • A memory card can only be disabled with a Message to Self.
  • Once a memory card slot is disabled, you lose all ability to communicate to a memory card inserted into the slot. This includes any diagnostic information.
  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 tab on the Message Configuration dialog box as described in the table below.
    This image shows how to configure the Config on a MSG to disable a controller's SD card in Logix Designer.
    IMPORTANT:
    These values are stored to non-volatile controller memory in such a way that the MSG instruction is not required to execute each time the controller powers up.
