Hello everyone.
I have a problem with the OPC UA communication between a self-programmed OPC UA server and an OPC UA client from Siemens NEO.
The data transfer to the client freezes after a few days.
This is noticeable as follow:
Value (no display)
Datatype Null
Source Timestamp 01:00:00.0000
Server Timestamp 01:00:00.0000
Statuscode Good
After browsing the OPC tag, the value will be updated again.
The server has a special feature: OPC tags alternately switch from the status code Good to BadResourceUnavailable for a longer period of time. The datatype changes from Double to Int32
Maybe someone has an idea what’s the reason.
Thank you for replying
Wolfgang
