Porter Posted March 6 Report Share Posted March 6 I've put together a wrapper to the Plasmionique Modbus Master library that makes communication with PLCs a bit easier. It could be used for just about any Modbus device, but I had PLCs in mind when I was developing it. What is easier? - Modicon-style addressing instead of data address and function code. - Data-type conversion built-in(eg. 32-bit float mapped to two U16 registers). Word swapping option. - Poll list and cached data block. Allows you to poll a range of registers then lookup and convert the values elsewhere. The code is up on GitHub: https://github.com/rfporter/Modbus-PLC-Client Its a rough draft at the moment. Comments are welcome and appreciated. 1 Quote Link to comment
