SAP PCo OPC Tag Reading

[Former Member]

Hi All,

Have a requirement like,

1.  Need to read the OPC tags configured in the (IntellutionGatewayServer) KepwareExOPC server and i am using the SAP PCo 15.0 to read the tags from that particular OPC but i face some challenges where i have added my notification to trigger the OPC read values from PCo to SAP MII 12.1. I have received the file in destination SAP MII but with the errors as "Could not evaluate Confitional node" . I have attached the same file please refer to it. I am not able to read the configured values. Can you guide me with what could have gone wrong in my configuration in PCo.

Hi Praveen,

Please check in your agent's Subscription Item tab, if the tags have been subscribed properly. Also, please review your Expressions in Expression Editor to check if the tag names are same as they are in the Subscription Item List. This error message normally comes if there's some discrepancy in the tag names in your Expression Tab and/or in the Subscription Item tab.

Regards
