FD1 Diagnositic Calls

The endpoints fd1.diag.... are used by Fieldpine internally to analyse and debug running systems. These calls are not available for public use and have additional requirements in order to be activated. Technically speaking, a different driver is selected to the standard FD1 driver when using these functions.

Fd1.diag is used on the connection between the support server and the SUT. The 3 connections on the left use the related fd1.support protocol. fd1.diag is the technical commands, while fd1.support is the higher level abstractions

The remainder of this page is primarily for Fieldpine use only.
