Use the
General
tab on the Add-On Instruction Definition Editor
dialog box to configure the general properties of an Add-On Instruction. The following table describes the parameters on the General
tab.Parameter | Description |
Name | The AOI name, which must follow the Logix Designer application IEC-1131 Name Standard. The name of the AOI must be unique. |
Description | A description for the instruction that contains a maximum of 512 characters. |
Type | The language type of the main logic of the Add-On Instruction (Ladder, Function Block Diagram, Sequential Function Chart, or Structured Text). For safety Add-on Instructions, the language type is restricted to Ladder. |
Change Type | Changes the language type of the main logic of the Add-On Instruction. If Class is set to Safety, the only available type is Ladder Diagram. Important: This setting takes effect immediately. Changing the type of an Add-On Instruction removes any existing main routine logic and replaces the existing logic routine with an empty routine of the new type. Scan mode routines are not changed. |
Class | The class designation for the instruction, either standard or safety. Safety Add-On Instructions may need to meet requirements specific to safety applications. This setting is available only in Safety controller projects. |
Revision | Designates the major and minor revisions of the instruction. You can use the Extended Text field to enter up to 40 characters of additional revision information. |
Revision Note | You can use this box to enter additional information about the revision, up to 512 characters. The note is not downloaded to the controller. |
Vendor | You can enter up to a 40-character Vendor name. |
Permission Set | Applies a set of permissions that controls access based on the permissions configured in FactoryTalk Security . The default setting, <Controller Inherited> , applies the same security settings that have been applied to the controller or project. |
Logic | Click this button to open the Logic routine. This button is not visible if the Add-On Instruction is source-protected and non-viewable. |
Copy all default values of parameters and local tags whose values were modified to all tags of this instruction type | Copies all the default values of the parameters, local tags, or members' default values, that you have changed, to all instance tags of this instruction type. |
