Do zou have a problem in the communication between HMI and PLC? What's the error message? Do you configure that system for the first time or it was running and then the problem happened. Please tell us more about your system. Regards,

Which is PLC settings (slotnumber of CPU). All setings must be the same in both devices. And you continue with details about your application... regards
