SNVT_str_ascii is supported using either a BI or BO LON Point Object Type and is read-only regardless of how it is mapped. Only a single LON point object is required to display the full 31-character ASCII text. The point object can be mapped using either the point Auto Discovery process or the manual mapping process. When mapped manually, make sure to use the structured Target Reference and not an individual field. The full ASCII text is displayed under the Hardware tab (Figure 1) of the point object in the Text attribute. The Text attribute can be placed on a graphic to easily display the ASCII text.
