Defining Add-On Instructions Chapter 2

• Program parameters that reference a module must connect to a module, and

cannot reference other module reference parameters.

• Module reference parameters must be program or Add-on Instruction

scope, not controller scope.

Tip: You cannot create a module reference tag. You can only reference modules using

an InOut parameter of the MODULE data type.

1. In the Controller Organizer, right-click an Add-On Instruction and

select Open Definition.

2. On the Parameters tab, in the blank Name box, type a name for a

parameter.

3. In the Usage box, select InOut.

4. In the Data Type list, select the MODULE type. This data type is for the

MODULE object, and contains the following information:

• Entry Status

• Fault Code

• Fault Info

• FW Supervisor Status

• Force Status

• INSTANCE

• LED Status

• Mode

• Path

For more information on the MODULE object, search the Logix Designer

online help.

5. In the Description list, type a description, maximum 512 characters.

This description appears in the instruction’s help.

6. In the Constant list, select InOut parameters check box you want to

designate as constant values.

Tip:

You can also create parameters by using the Tag Editor, New Parameter or Local Tag dialog box, or by right-clicking a

tag name in the logic of your routine.
