In order to standardize the application of fieldbus device in power plants

the design specification of diagnosis points of fieldbus device was proposed after analyzing the actual application situation of fieldbus devices in power plants.The configuration normalization of the fieldbus device in control system was also introduced in detail.Taking the EMG electric actuator for example

the selection principle of the module

the introducing format of the diagnosis points and the naming rule of each point were introduced.Moreover

the normal configuration of the fieldbus device and the standardized one was compared by taking the RAGA electric actuator as an example.The results show that

using the new configuration scheme can realize real time device status monitoring

reduce the maintenance cost and improve the reliability of the fieldbus device.
