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.
