PLC S7-300 connect with KEPServer OPC Server and GE SCADA Proficy Cimplicity HMI

[@rockydo123]

Hello, thanks for your detail instruction. I have a question as i want to be clarified. I have a PC where i run an application for material inspection and it have OPC UA install as a server. And i want to write some data to PLC s7 300 datablock (ready, fault, counters…). Do i have to do anything with the PLC (beside create the DB for data to be written)? Or i just create data points in OPC server with write access. Thanks in advance.

Good morning, excellent explanatory video on how to connect a PLC to a SCADA system or an HMI, it helped me a lot when it came to clarifying how this type of communication works. Friend I would like to ask you a question, I am working with a small project in python and I want to communicate with a PLC s7-300, but my CPU312C does not have a TCP/IP connection, only by serial cable and a USB converter, I have investigated how to do it with modbus and its library for python called pymodbus, but it has been difficult for me to understand it, then I investigated about OPC servers and I see your video, do you have knowledge on how to generate the communication of this PLC with a code in python? And if you can guide me if there is any python library for an OPC server, or if you know how to understand the modbus RTU? Thank you for your time and your response.

Good evening, greetings, I have followed your tutorial and it has helped me to learn about opc servers, however I have a problem, when creating my "tags" in KepServerEX, I check their quality through the client and it tells me "Quality Bad", how can I solve that? I would appreciate your help please. Kind regards.

Dear sir, Please check and configure the PG/PC interface to be correct function then try again follow my tutorial. Thanks

@@generaltechnologyknowledge5165In the PG/PC interface configuration I have already used PLCSIM (MPI) and PC adapter MPI, and with both I can't get a "good" quality
