SAP MII PCO -typeTagRetrieve Query

Hi,

I kindly ask for some support on an issue that I faced while upgrading my customer SAP PCO version from 15.1 to latest 15.3.

During the last 5 years we have developed a lot of SAP MII (15.1 version) code using PCO query (TagRetrieveQuery) to read values from PLCs (connected through OPCUA agents).

With PCO 15.1, the output of the query is an xml with one row, containing all selected tags (let's say: 10 tags).

Upgrading to PCO 15.3, the same query outputs a xml with 2-3 rows. Tag values are distributed on the multiple rows. Some values are good, some are "NA":

This kind of answer makes subsequent MII BLS code unusable.

On PCO 15.3, “package size for services” is set to "0" (no limits) for READ/WRITE and BROWSE.

I will appreciate any suggestion, as in these conditions the upgrade to new PCO is impossible.

Thank you!

Hi Mauro,

I would suggest opening a support ticket and this will be forwarded to the development teams for testing.

Thanks
