Greetings everyone,
I encounter a lot of problems to connect to the PLC. For a couple of days, I had to find by myself the port number ...
For now, I managed to connect to the automaton, but now, impossible to connect to the PLC (and no documentation was given to me).
As far as I understood, I do need an MPI address but I have no clue of where to find it, to connect to the PLC, I simply had the rack and slot values.
Strangely, by using the UserTransport protocol, I can connect to the PLC but my program crashes by trying to read a value...
According to this site : https://alexsentcha.wordpress.com/l...-plc-2/vb-net-exchange-data-with-siemens-plc/
I have to use the ISOTPC protocol but the connection fails...
The automaton mark is Siemens S7.
Thanks for your help
