Failure Diagnosis and Hot Plug
Field Power Loss
Diagnosis
Bit2 in the diagnosis bytes (Bit0~Bit7) reported to the module is used to indicate the
information on field power supply detection. When Bit2=1 indicates field power loss, then
Bit2=0 indicates field power recovery. The field power failure diagnosis only reports once
separately when a failure occurs and the fault recovered.
