The FDIA system project brief was to implement around 50 function blocks in IEC 61131 to provide a series of fault detection and safety features that could be re-used within different projects.

Each function block has a detailed specification and also implement was a test suit to test the 50 function blocks operation against the expected outputs. This FDIA was implemented using the IsaGraph product.

The output from the project:

1. ★50 IEC 61131 Function Blocks
   

2. ★50 Test Programs
   

3. ★Detailed Test Specifications.
