OPC-UA device protocol - cyclic read vs. subscription

Hi there,
I would like to add some information about this topic.

I am not sure if it is a good way to reply to this topic. Any suggestions are welcome.

First: a correction.
As defined here, the deadband in Percent is not a corresponding change of %-Value of the current value but rather depending on the EU-Range.

e.g. 
EU-Range High = 100.0
EU-Range Low  = 50.0

Deadband Percent = 10%  --> **deadband value = 5.0**   // ( hi - low ) * deadband / 100.0

Calculation is done based on the last transmitted value

Examples:
The information in the original post suggests that it would need to change from 
50.0 to 55.0 
or
90.0 to 99.0  (10% of last transmitted value)

**Correct**
50.0 to 55.0
or
90.0 to 95.0

Second:
There is a problem in the Current UI of the device-management (as of UI: 1011.0.12)
In the section of the device-protocol where one could configure the deadband of the protocol, it does not work (there exists a workaround for e.g. Postman)
It is supposed to be solved in
UI: 1011.0.15 upwards
