I doing update modbus(C++) driver for receive alarm and warning code from motor.
I try to query alarm code using "0080h" register address but motor response "0000"
But motor response no alarm.
Below query message format is not correct?

Ex)
10:15:57.083 [Send] 0203007f0001b5e1 -> Send : Query Motor Status
10:15:57.107 [Recv] 02030240810de4 -> Response : Alarm Status

10:15:57.107 [Send] 02030080000185d1 -> Send : Query Alarm Code
10:15:57.131 [Recv] 0203020000fc44 -> Response : No Alarm Code

Hi EvanBae,

For the present alarm the upper value will always be 0000 because all the alarms codes can fit in the lower registry. Therefore try reading the lower present alarm register 0081h.
