Thanks. But this is just theory. If any one has tried reading data from RS 485( 2 wire ) from any industry grade controller using DK 300, please share results.
We were able to get results with RS 485( controller end) to USB converter ( DK 300 end ). But a direct 2 wire, RS 485 connection between controller and DK 300, yields no data or results. We were trying Modbus/RS 485.
