This way, please make sure the good agreement, the agreement means we can give you looking for something simple, or give you a general, you have to tell in front of a pile of people, I don't know for

And PLC operating
Instructions: 1. The text that is the string concatenation, parsing string, divided by a newline, MSDN serial port routines as well
2. Modbus protocol: although this can also use the general, but I think you like those with unclear, so directly to nuget looking for finished product realized (nuget basic demo, it is good to build a lane directly)
3. The following pseudo modbus protocol, those guys do this kind of agreement, agreed to, you say he is the modbus, he's not modubs, you say is not the modbus, he grows up with modbus is similar, so you can only connect and byte [] according to the rules after parsing, the things you need for the,

So, first to us, what do you do by what agreement,
