Hi,
I am working on a prototype where the customer wish to connect a Modbus RTU device to the Internet through a low cost solution consisting of an external converter. The Modbus Slave would reside in the serial device, and the Master would typically reside on a remote computer/handheld unit.
I have managed to find a Ethernet to Serial device that simply just translates between the two transport layers in the price range of 70 $ which is the target.
The client dont want to implement too much extra code on the serial device side.
My question is if it would be possible to simply wrap a Modbus RTU packet in the TCP packet (On the Master side) so that the converter can just strip the TCP packet and send the RTU packet to the serial device?
In the opposite direction, the serial device would just send a Modbus RTU message to the converter which will dress the packet in a tcp/ip header and send it to the remote computer/handheld device which in turn would parse the message.
Or am I thinking completely wrong?
Please dont respond with answers like considering buying this or that router, because I have already ruled that out.
How my question makes sense.
Thanks!
