l

Condensed Mode: In this mode, the server tags created by automatic tag generation follow a group/tag hierarchy consistent with the tag's address. Groups are created for every segment preceding the period.

l

Expanded Mode: In this mode, the server tags created by automatic tag generation follow a group/tag hierarchy consistent with the tag hierarchy in RSLogix 5000. This is the default setting. Groups are created for every segment preceding the period as in Condensed mode, but groups are also created to represent logical groupings.

Note: For more information on the groups created, refer to Tag Hierarchy.

Note: To enable this functionality, check Allow Automatically Generated Subgroups in Device Properties.

Allen-Bradley ControlLogix Ethernet Driver Help

If an older OPC server version was used to import tags via L5K/L5X import and no tags were clipped due to the 31 character limit, do not select this option. Similarly, if tags were imported via L5K/L5X with OPC server version 4.70 or above, do not select this option.

l

Tag Hierarchy: This parameter specifies the tag hierarchy. Options include Condensed and Expanded. The default setting is Expanded. Descriptions of the options are as follows:

Descriptions of the parameters are as follows:

l

Impose Array Element Count Limit: When checked, an array element count limit will be imposed. Tags in the controller can be declared with very large array dimensions. By default, arrays are completely expanded during the tag generation process, thus becoming time consuming for large arrays. By imposing a limit, only a specified number of elements from each dimension will be generated. Limits only takes effect when the array dimension size is exceeds the limit. The default setting is unchecked.

l

Element Count Limit: This parameter is used to specify the element count limit. The default setting is 2000.
