Hello everybody,
I am working on a project which has HMI FTView SE 13 (Local) and controllogix L71 PLC. I have a question how does PLC detect a failure communication with HMI? Whenever HMI app closed or not running, for example the PC that HMI is running on stopped, PLC need to detect that. Is there any special tags to do that?
Thank you for helps
