Application name

A PI trust can require a specific application name. When you specify an application name in a trust, you have to use the appropriate format for the connection type:

• Applications that connect through the API Connecting PI API applications send an identifier called an application process name, or procname. This is a four-character string with an E appended. For example, the procname for the Perfmon Interface is: PIPeE

  Note: PI API versions before 1.6.0 always send a five-character string: 4 characters plus a capital E. For PI API versions 1.6.0 and later, the name can be up to 8 characters, without a trailing capital E.

• For applications that connect through the SDK, use the full name of the connecting application, including the extension, but not the path. For example, the application name for the ICU is: PI-ICU.exe

If you are running the same PI interface on another Data Archive server, then you can use PI SMT to determine the correct application name. Select Operation > Network Manager Statistics. Find the interface in the list. The application name is listed in the Name field.
