Hi,

I'm developing an equipment to read voltage and current curves and I want use MODBUS to transfer this data to PC.

Each curve will have 512 poins. Can I use MODBUS? If yes any suggestions?

Thanks

 

Maybe, but . . . .

The Modbus standard lists a couple of Function Codes, FC20 and FC21 (decimal) (14 and 15 (hex)) named Read File Record and Write File Record, respectively.

The Modbus Application Protocol V1.1b has the specs
