My dearest colleagues, I need some help with communication between PLCs and SCADA and I would like to ask if someone could help me.
If you have one PLC type Modicon M340 Schneider Electric with communication NOE module for Ethernet, and on the other hand you have one PLC type S7-300 Siemens with CP 343-1 Lean for Ethernet, and you have one SCADA, for example VijeoCitec, Schneider Electric.
Now, if you want that SCADA read data from both, Schneider and Siemens PLC, do you need Schneider OPC server to read data from Schneider PLC and Siemens OPC server to read data from Siemens PLC, or SCADA can read directly from Schneider PLC and you got to have Siemens OPC server to read from Siemens PLC.
Is there OPC server which can read data from any PLC?
Thank you in advance for your time!!!
Greatings!!!
