倍加福光電開關(guān)倍加福光電開關(guān)Failure margin check
During commissioning or a scheduled outage, the FDH-1 is the first of its kind to check the resistance of fieldbus communication against electromagnetic interference. With the Fieldbus Diagnostic Handheld, you determine the failure margin of installed field devices individually, or all at once, on a working segment in just a few steps. During this test, the FDH-1 adds distortions to the communication signals and determines the maximum values for reliable communication. The accompanying report is created automatically. A good failure margin is the hallmark of reliable communication.
