Create trusts

If you are installing the PI UFL interface on a node separate from Data Archive, you must create trusts for the following programs:

• PI UFL interface

• PI Interface Configuration Utility (PI ICU)

• PI SDK (if you are using PI annotations, automatic point configuration, or digital set or digital state creation)

• PI SDK or PI API buffering (if running against a Data Archive with high availability features)

Procedure

1. Start PI System Management Tools (PI SMT) and connect to the Data Archive.

2. Select Security > Mappings & Trusts.

3. On the Trusts tab, right-click and then choose New Trust when the Add Trust wizard opens.

4. In the Add Trust wizard, specify a meaningful name and description.

5. Configure settings as follows:

   Program	Type of Trust	Application Name
   Buffering	PI-API application	APIBE (PI Buffer Server) or pibufss (PI SDK buffering)
   PI ICU	PI-API application	PI-ICU.exe
   PI UFL interface	PI-API application	PI_UE
   PI UFL interface	PI-SDK application	PI_UFL.exe

   The PI identity you specify for the trust must have permission to update the PI Module Database. For maximum security, specify the network path using a fully-qualified node name or IP address plus netmask 255.255.255.255.
