●MODBUS registers address:
Function parameter No. (DEC) MODBUS registers address No. (HEX)
(ENTER to save data) (00FFH)
(Only write-in data) (0001H~001FH)
(Only read-out data) (0020H~004FH)
P0.00~P0.22 0100H~ 0116H*
P1.00~P1.16 0200H~ 0210H
P2.00~P2.34 0300H~ 0322H
P3.00~P3.26 0400H~ 041AH
P4.00~P4.25 0500H~ 0519H
P5.00~P5.36 0600H~ 0624H
P6.00~P6.11 0700H~ 070BH
P7.00~P7.18 0800H~ 0812H
P8.00~P8.04 0900H~ 0906H
P9.00~P9.09 0A00H~ 0A09H
PA00~PA.09 0B00H~ 0B09H
Pb.00~Pb.06 0C00H~ 0C08H
PC.00~PC.22 0D00H~ 0D16H
Pd.00~Pd.19 0E00H~ 0E13H
PE.00~PE.12 0F00H~ 0F0CH
PF.00~PF.03 1000H~ 1004H
(Reserved, for parameter
extending)
(1100H~FFFFH)
*Note
In the function table, the MODBUS address coding rules:
High 8 bits HI = (Parameter group number + 1)
Low 8 bits LO = (Function Parameter number)
The function parameter P0.11 can be only read. In addition, function group PF can’t be
read and written.
Reading reserved address will return communication error code “02 H”.
