Hi @Serhioromano, 1st question: I guess so, industrial product has many option to define communciation between Siemens PLC to SCADA, even thur OPC standard or anything. 2nd question: You can choose whatever you want, my perspective is S7 communcating directly to my PLC, if they are a small size of blocks and posibly handle them. Hope it helps
I have an application that has to be able to read data from all Siemens PLC like 200, 300, 400, 1200.
I am not good at Siemens I am more like WAGO\Codesys\Modbus world user. I always thought that PROFINET is an analog of MODBUS in the siemens world. Now I find this library. Another protocol?
On another site, I read
That sounds reasonable. Does that mean that people do not use PROFINET to communicate to Siemens PLC for SCADA? My app is a little SCADA for a particular project with S7 1200 PLCs. I need to show a few tags only. Why would I choose S7 over PROFINET?
