Modbus Address Mapping
The standard Modbus address ranges are as follows:
Digital Outputs:
00,001 - 09,999 (Coils)
Digital Inputs:
10,001 - 19,999 (Discrete Inputs)
Analog Inputs:
30,001 - 39,999 (Input Registers)
Analog Inputs/Outputs:
40,001 - 49,999 (Holding Registers)
Due to memory limitations, the RTU does not use the complete Modbus address range. The RTU responds
to requests for Input Registers (30,001 - 39,999) as if they were Holding Registers (40,001 - 49,999
respectively). Local registers, analog and digital outputs can be read and written to as indicated below. The
Modbus addresses that can be read from an RTU are listed below.
Kingfisher RTU
Modbus Slave mode
Modbus Master
Device
Can w rite Modbus addresses 41001 to 43048 to RTU
(Holding Registers 1001 to 3048 = #R1 to #R2048 respectively)
Can read Modbus addresses 40001 to 40512 and 41001 to 43048 from RTU.
Analog I/O (eg. AI-1/4/10, AO-2)
Note: IO-3/4 analog inputs start at Ch 2.
IO-3 analog output is channel 6.
