Modbus Communication Protocol
40
corresponding to function code parameter’s group internal code. For example: F3.21
function code’s communication address is 0315H, 03H is the hex form of group
number 3, 15H is the hex form of group internal code 21.
F0.00~F9.11 communication address is 0000H~090BH, fault record parameter
initial address of Fd group is 0D00H.
