When I go PLC - Upload station to PG and select the IP address of the CPU (it finds it), I click OK and get the message "Online: The connection to the target module cannot be established" followed by "The connection module could not be configured".
However, in my project I created a hardware configuration containing only the PS and CPU, and I could go online with it. Not only that, but when I go online it asks me if I want to use the saved version for diagnosis or upload from PLC - I click upload from PLC and indeed I can see the PLCs hardware configuration.
So it means there is a connection and they are talking. So why am I getting those messages?
