In its recommendation NE 107, NAMUR has uniformly defined four status signals for all field devices including device failure, maintenance requirement, outside the specification and function control. This enables identical condition visualization for all field devices that are based on the DD/EDD device description package – irrespective of type or manufacturer. The SIMATIC PDM Maintenance Station records the diagnostic states and condition data of the field devices, which are implemented by the device manufacturers and described in DD/EDD. It cyclically and autonomously reads this information from the field devices and reports any maintenance requirements, requests or alarms based on the NE 107. The maintenance staff is thus immediately informed and can act or respond in a timely manner.
