Hi Community,
I am testing ctrlX IO Analog Output with ctrlX Node-Red datalayer subscribe node. however i am not able to read the Analog Output value using Datalayer subscribe node see below. But using Datalayer request node is working well. Is this a normal behaviour?
Just tested your case with version 1.20 and everything is working fine:

For version 2.4 it could be related to a known bug. Please enter the default values (instead of leaving it empty) in the subscription configuration:
