Hello. I am expert in PLC S7 (300-400, 1200-1500), Industrial Communication.
I am also expert in C/C++, C#, QT, ...
I can do your job well.
With your project, you can use one in belows:
- Modbus TCP/IP: We implement a modbus slave on PLC, you can use a modbus library in program on PC to communicate to PLC. I will modify so that PLC only response some requested clients.
- Implement a new protocol on PLC, we have to write a library (C/C++, C#, ...) that you can use in program on PC to communicate to PLC. PLC lso only response some requested clients.
I can do program in Step7 or TIA Portal, language is SCL or LAD.
Could we discuss for more details? I will review then let you know about Price/Time.
I prefer work for fixed price job.
Thanks.
