For operators it’s very important to know following Status information:
1. Status of communication channels (running, stopped, error etc. )
2. Device communication status (connection is OK, communication fault)
Which Status information is available for visualization in the Web-browser?
If communication is stopped, status of device channels become Unreliable (5) within 5 minutes by default. In case of communication error channel status is Undefined (0).
You can visualize this information as needed. Anyway visualization uses input channel data.
And so I can make some formula that check any variable, and when is unreliable I have the “lost connection alarm” can you write the formula? If ( channelx is unreliable or undefined) Val = true ; else Val = false
