Use item prefixes

In addition, you can configure an item prefix for an ArchestrA group. This prefix, which is added at runtime, can simplify item naming for ArchestrA groups in some situations.

Assume the item prefix for the ArchestrA group "Blower" is "Blower_". Item names added directly through the data source remain unchanged, but the same items added through the "Blower" group are simplified.

OPC Client Syntax

ArchestrA.Blower_001.Temp1 (at the data source level)

ArchestrA.Blower.001.Temp1 (at the group level)

DDE/SuiteLink Client Syntax

Gateway|ArchestrA!Blower_001.Temp1 (at the data source level)

Gateway|ArchestrA_Blower!001.Temp1 (at the group level)

Note: Do not configure an ArchestrA group name to be identical with an item prefix. This name clash can cause unexpected behavior. Identical means the same in a case-insensitive manner.
