Modbus Register Assignments
Section 7 - DP606A and DP612A Modbus Register Assignments
All accesses to the DP606A and DP612A database information is made thru the
following Modbus registers.
Data types:
R – single 16 bit register (may be Boolean, byte, char, int16 or uint16 data)
L – dual (32 bit) register (may be int32 or uint32 data)
F – IEEE Floating point value
B – Byte Array
All data is transferred using Big Endian formatting, where the most significant byte
is transmitted first.
