I already know.
FuncCodeReadDiscreteInputs = 2
modify
FuncCodeReadDiscreteInputs = 3
because FuncCodeReadDiscreteInputs is const.
I must edit lib code.
from modbus.
@chengziqing Would you please clarify what the issue is? Did you got i/o timeout when using ReadDiscreteInputs or ReadHoldingRegisters?
From what you've suggested, I think your server does not support function code ReadDiscreteInputs (0x02)?
