Enhancements to the Foundation fieldbus specifications include:
- Addition of a test procedure for isolated couplers to the existing Foundation fieldbus Coupler Test Specification. Registration of isolated couplers is now possible.
- Improvements to the H1 Physical Layer Conformance Test Specification based on Action Requests received during the last few years. The most significant changes include the addition of a receive jitter test case and a device-coupler interoperability test.
- Updates to the H1 Physical Layer Test Specification to remove obsolete profiles and align new references in the document with the current International Electrotechnical Commission (IEC) specifications. Coupler profiles were also added to the test specification.
