Hi!
I don't think it's possible but you never know.
Is it possible to see who is polling data from my CPU? For instance is a scada system, another s7-1200 or OPC client polling data directly from a datablock. I have nothing configured in the s7-1200 it's just the datablock that is accessible to other. I'm thinking of using this as a help to customers if they try to read data from the PLC, and then they can see in the HMI if they are succesfully connected.
Thanks
/Tim
