Limitorque actuators with Foundation Fieldbus can act as a link active scheduler and time master for regulating communication on a fieldbus segment. The Fieldbus Foundation has tested and registered the Limitorque Device Description (DD) files to ensure interoperability with registered devices from multiple vendors. In addition, The FDT Group has certified the DTM (Device Type Manager) for use with both standalone and non-standalone frames.
