Hi All,


As part of a migration project we have migrated our existing PI server from 2015 to 2018 version and data source for these server is PI OPC DA and PI Modbus. We have no issues with PI OPC DA interface and data is updating fine. But when it comes to PI Modbus tags they are not updating as per the configuration.


Below is the Tag configuration.




In the old server the tags are getting updated once in 4 hours according to the compression settings.


Archived values from Old Server:

Archive values in New server:


Could any one help us on this situation?.


Thanks & Regards,
