Excel security features for add-ins, ActiveX controls and macros allow you

Excel security settings may conflict with certain FactoryTalk Historian
DataLink features:
 FactoryTalk Historian DataLink is an Excel add-in. Security settings

 PIPutVal (page 146) spreadsheets use macros and require that macros

need to reduce or eliminate Excel security settings depending on how you
plan to use FactoryTalk Historian DataLink .
For further information on Excel security, consult Microsoft Excel online
