synchronisation and Dead-band support in OPC-UA in IoT edge

Vivek Sagar Pandey 386

Hi There,

We are running OPC-UA server simulator ( developed with Python) in Azure VM with IoT-edge runtime.
is it possible to:

Implement Dead-band concept for reading the values?
synchronization polling of the tags/nodes? using OPC Publisher or any other module.

Please let me know the possibility for the same.

Hi @António Sérgio Azevedo ,

No, we will not be using the microsoft IIOT solution as it as. We will be following it's architecture to create our own required solution. Like, using IoT hub, IoT edge etc to take the data from device and vice versa.

Answer 1

@Vivek Sagar Pandey Apologies for the delay in response. Please find the below answers for your queries received from our product team.

Implement Dead-band concept for reading the values?

Currently, no version of OPC Publisher supports deadband (or DataChangeFilter), As mentioned on the Git page, it is on our backlog and there is no exact ETA to share.

synchronization polling of the tags/nodes? using OPC Publisher or any other module.

You could use the OPC Publisher module in standalone mode without the Industrial IoT Platform, it uses OPC UA MonitoredItems concept to transmit data changes of OPC UA nodes into the cloud.

Please let us know if that helps or have any further queries. We would be happy to address your queries.
