Communications method for diagnosing industrial equipment links to a field device linked to a central control via a communications link and incorporated in a facility related to this method

摘要

A field device (3) periodically transmits diagnostics data from the field device to an operating terminal (4) via a global network (1), e.g. the Internet, independent of a communications link (6) used to link the field device to a central control (5). Devices are linked to the operating terminal for evaluating captured diagnostics data.
