The Alias field allows a user to specify a 'short-name' for an OPC item. This can be especially useful when dealing with a control system with a hierarchical name space that results in long OPC item names.
In order to modify an Alias the user must have the 'Modify Item' privilege.
Tip: Aliases can be batch loaded from a CSV file using the Batch Operation facilities. If no Alias is specified for an OPC item when it is created the Alias will be defaulted to the full OPC item name. Aliases can be modified 'en mass' via the Batch Modify option.
Note: In order to work with Aliases instead of the full OPC item name, the user must enable the 'Use OPC Item Aliases' User Preference.
