Modbus scanner not working? Siemens HMI implementation. #34
Hello,
I am trying to use the Modbus IP lib to connect to an Siemens HMI.
As of now no luck to get it working.
After a lot of testing, I found out that I could not make a connection with the CAS modbus scanner.
If someone can help me further, it would be very appreciated
Kind regards, Raphael
