How to read historical data from opc ua or hda shop floor system in SAP DM ?

[m_ehab]

In SAP DM,

please any one can guide me how to get a tag value at specific timestamp ?

The indicator in sap dm is mapped to a tag in a shop floor system of type opc ua or hda

For example, the operator runs a production process any time and we need the tag value at 7 AM to be used in other services in the production processes.

Thanks in advance

thanks harry

I know this scenario, but what if the production process failed to read the indicator because of any connection issue.
