The FOUNDATION fieldbus device coupler test specification includes criteria from the international IEC 61158 standard and additional functional tests such as input impedance, short-circuit reaction time, and bus voltage consumption. The specification is designed for coupler manufacturers to perform a standard set of tests against their implementation. A team of volunteers comprised of current members of the foundation who supply coupler products, as well as end users employing registered couplers, developed the test cases.
The Fieldbus Foundation’s Director-Fieldbus Products, Stephen Mitschke, commented, “The Fieldbus Foundation is committed to rigorous test procedures for all Foundation devices, hosts and components. Our device coupler test specification is intended to provide a high level of robustness in fieldbus systems. The resulting registered products are tested to perform optimally with registered power supplies and conditioners, as well as registered H1 cable.”Mitschke added that the latest enhancements to the Foundation fieldbus physical layer specifications will provide end users with greater confidence that registered fieldbus equipment can be employed in a tightly integrated, interoperable control system architecture that is well suited to the most demanding industrial environments.
