UMG 96RM
Example: Reading the L1-N voltage
The L1-N voltage is stored in the measured value list
under the address 3166. The L1-N voltage is stored
in INT format.
The UMG 96RM device address with the address = 01
is adopted here.
The "query message" then appears as follows:
Description Hex Note
Device address 01 UMG 96RM, address = 1
Function 03 “Read Holding Reg.”
Start address Hi 00 0200dec = 00C8hex
Start address Lo C8
Disp. Values Hi 00 2dec = 0002hex
Disp. Values Lo 02
Error Check -
The "response" from the UMG 96RM can then appear
as follows:
Description Hex Note
Device address 01 UMG 96RM, address = 1
Function 03
Byte meter 06
Data 00 00hex = 00dec
Data E6 E6hex = 230dec
Error Check (CRC) -
The L1-N voltage read back from address 3166 is 230 V.
