Disable an Ethernet Port with an MSG Instruction

You can use a
CIP™
 Generic MSG with a Path of THIS to execute this option. You cannot use this MSG instruction to disable an Ethernet port on another controller.
  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 the MSG Configuration dialog box to disable a controller Ethernet port 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.
