SAP MII / PCo and kepware Local Historian

Is there a way to query the history value's of a Kepware Local Historian?

In PCO I can only connect to the OPC server but not tot the historian.

    Hi,

    After you connect to kepware via PCO query, have you tried the query mode as "TagRetrieveQuery" and further View as "Event" ?

    Hi,

    Event would only give you archived data not historical data. Interpolate should be used to get history values along with tag retrieve.

    Hi,

    With DA source configured for the kepware you can access Kepwaree real time data . As mentioned local historian , I suppose your Kep server is installed with HDA ; for this you need HDA source system configured and from MII you can have the history values retrieved using POC query template with appropriate DS for the HDA agent.
