FOUNDATION™ Fieldbus H1 ITK 6.5.0 Released!

Dear <<First Name>>:

Thank you for your continued support of the FOUNDATION Fieldbus H1 ITK. 

FieldComm Group is excited to announce the release of version 6.5.0 of the H1 Interoperability Test Kit (ITK) for testing FOUNDATION Fieldbus devices. The latest version of the test kit provides maintenance level improvements to system and hardware support. 

What's new?

  • All libraries and test cases are now compiled using Microsoft Visual Studio 2019.  
  • Bug Fixes 

In release 6.3.0, we introduced Standard Connection Points (SCP) test cases. Since that initial release, additional test cases have been added that require a firmware update to the Test Function Block. License holders with an active Product Service Program for their H1 ITK need to request an upgrade for their Test Function Block in order to fully execute SCP tests with their devices in development. 
Contact Support for further assistance if you have not yet inquired about the updated Test Function Block.

To obtain detailed information or download the datasheet, please read the product support articles on For other questions, please call FieldComm Group at 512-792-2300 or e-mail
