Hello,
I'm trying to write a little app to poll a PLC (AutomationDirect Productivity 2000 specifically.) I've found two libraries that seem to work (EasyModbus and NModbus,) but neither of them can do 32 bit register addresses.
The Modbus spec says that you can use registers 40,000-49,999 for holding registers, and also 400,000- 465535, but both of the libraries I use can only do the 40,000 range.
The guy working on the PLC swears up and down that the PLC will not let him use 40,000- 49,999, only the 400,000- 465535.
Does anyone know of a library that can do the 400,000- 465535 registers?
Thanks
