QTcpSocket to PLC S1200
-
Hi, I have been doing a HMI interface on Linux. I found the Snap7 library but don't works fine, is there any way to connect S1200 PLC by QTcpSocket (or something similar) and read a specific DB or input?.
I 'm new and some example would be very helpful for me. -
It looks to me that the Siemens S7-1200 device uses PROFINET. There is a protocol implemented on top of IP with either UDP or TCP. While you should be able to connect using a QTcpSocket (or QUdpSocket), most of the work will be in the protocol. That is what Snap7 provides.
Generic Qt networking examples should be enough to cover establishing TCP/UDP communication. Implementing the S7 protocol is definitely well outside the scope of Qt forum.

What are the issues?
The problem is that you cannot use it with Qt?
Are you able to use it standalone?
