Help for custom Driver

[quote="GermainN"]Hi,
As I saw in a other post, U say that if we want to make a real driver we have to make a AbstractNioDriver, so I'm going to do so.

By "real" driver I mean one that talks to a PLC. For a driver like this extending NodeMapDriver, or even better the new AbstractTagDriver, is perfectly suited.

When you create a DataValue object you can set the source timestamp. Use the public DataValue(Variant value, StatusCode statusCode, UtcTime sourceTimestamp, UtcTime serverTimestamp) constructor.

Not from a driver, that's a SQLTag property, not an OPC property.
