SAP PCO connector - how to tag name using point id from OSIsoft PI

[former_member437258]

Hi,

We are using MII/PCo connector to get tag data from OSISoft PI system. User configures the PI tag name and Point id in MII application through an MII screen. The Point Id is unique identifier in PI system. Some times user changes the Tag name in OSISoft PI, but they don't update the tag name changes in MII application. Need to develop an MII interface program to get the changed Tag Name using Point Id from OSISoft PI system. I did not find any direct query or function in MII/PCo query which can return a Tag Name using Point Id. Is there any function or method available in MII/PCo query which can get this information?

Environment details: MII 15.4, PCo 15.3

Thanks,

Anil

Using a sturdy ruler, rap the knuckles on the hand of the user!! What the heck is a user doing changing the names of the tags? The people responsible for naming the tags should also be responsible for the connection and subscriptions in PCo. Not some random user.

Does your client have Change Management?

Hi Mike,

The PCo Query Mode "Metadatalist" returns all the attributes including point id. But there is no function or method which can take an attribute like "Point Id" and return tag name information.

Have checked with OSIsoft for a suggestion, they provided an sdk function which takes point id as input and return tag name. Tried to call that function in "TagFixedQuery" mode using call directive. But it did not work.

Point ID is likely to be an attribute of the tag. I do not have a system up and running against OSIsoft PI, but I think a Tag Query or possibly a PCo Query would provide access to the attributes.

Might also want to reach out to OSIsoft for their suggestions. They have a lot of tools and participated with SAP in the development of PCo (and UDS before PCo). They should be able to help resolve the issue you face. HOWEVER, Change Management on the PI Historian is your real issue!
