Yeah,

So far the only protocol I worked on, that supports this "quality of data" feature, was the
delta-v protocol. For all otbers we would have to provide the constant max value.

Unfortunately their was the only driver I wasn't able to finish. As I have no hardware available.

So this feature was discussed, but never implemented.

This is not a simple questing and depends on the protocol and device you are using. What are
you using?

Ah, forgot: and is there a status available? Valid/invalid/good/bad indicator of a plc value?
