Logging DTL with OPC UA

Hello,
I have a PLC program which send the DTL from the PLC, although I can log the timestamp based on the SQL side, is there anyway to log DTL directly from PLC to Kepware with the new/upcomming updates ?

Greetings,

Sounds like Siemens.  DT (Date and Time) is supported, but I believe DTL (Date and Time Long) is still not.  I also believe this is true for Siemens TCP as well as Siemens S7 Plus. The workaround would be to switch the data type in the PLC to DT.

Regards,

Mohit
