Designate a Constant in the Tag Editor
The Constant column on the Tag Editor window lets you designate tags that
cannot be modified in the RSLogix 5000 software program. The Constant
property applies to an entire tag; all members of the tag take on the same
setting. The Constant column cells are blank for members of the constant tag.
An error message displays if a user tries to change the data type of a constant
tag to a data type that cannot be constant.
Follow these steps to add a constant value in the Tag Editor window.
