ODBC plug-in for KepServerEX 6.12 OPC DA server

ODBC plug-in for KepServerEX 6.12 OPC DA server

Product: KEPServerEX 6.12.325.0 + ODBC plug-in

 

I use ODBC plug-in to upload data from MariaDB to KEP OPC DA server. It is working very well.

 

But  the timestamp of a tag on OPC DA server is not updated when the value on MariaDB is not changed. 

 

I'd like to make the timestamp updated always no matter whether the value is changed or not.

 

Is it possible? Please let me know how to do.

Thank you for contacting us.

 

In OPC DA(Data Access) Specification, data publishing depends on either Value or Quality(VQ) change and not on Time change so technically this is not possible to publish data on time change. 

 

BR,
