Hi PLC talk people,
I have a beginner question.
I am looking at requirements to build a cloud hosted web application that can connect to a PLC (in my case a SIMATIC 300).
The web application needs to send commands to and receive events from the PLC, I would like to know what infrastructure you would recommend we investigate.
I imagine the following.
1. The PLC is running an OPC-UA server.
2. We have OPC-UA PUB/SUB MQTT Broker.
(does this run on a cloud server? I assume a router on premises would need to be in the middle).
3. The Web application can authenticate with the OPC-UA Broker and subscribe to events, publish commands.
We would like to be able to visualize the equipment operation from the web application. this part we are completely comfortable with.
I imagine there are massive gaps in my description.
Would you be able to point me at areas we need to consider.
Thanks
