Dynamic Value Registers
Actual value registers start at 1000, read by Function
Code 04.All the dynamic value registers are 32-bit in
length. Hence, query of any variable results in two
Modbus register reads, each of 16-bit length. Even
numbered register holds upper-16 bits; Odd numbered
register holds lower –16 bits
Example: To find out Phase-A SOS, A Modbus query to
read 1002 and 1003 registers need to be sent to SMR2
by the master.
There are 32 bits in this data. The upper-16 bits would
appear in register 1002 and lower-16 bits in register
1003 as a part of the response.
