Function Blocks rely on their Transducer Blocks to be configured properly, otherwise the Function Block may not go to a selected mode.

The ITK requires a detailed configuration (*.INI) file for the device. This file must include sections and parameters for every Transducer Block that is required for the device's Function Blocks to operate normally and be "testable".


If test cases at or just after i0402_50 in the certification schedule begin to fail because blocks under test "will not reach mode", it is most likely because a Transducer Block was left in OOS mode after the end of test case i0203_02. The EXAMPLE.INI file in the root folder of the ITK (Release 6.2.0) has examples of how to fix this problem, and the help documentation for ITS has been updated to describe this problem more clearly.
