I’m getting the following error …
[quote]Message: Write to SQLTag [[ISTP]MyTagName] failed with code [Bad_NoDataAvailable] - HRESULT: 48000
… whenever I attempt to write to the SQLTag, however the value will be accepted regardless. I’ve got the tag within a Transaction Group. If I right-click the entry and select Write to item, I get the above error. Additionally, I’ve got the tag set up within my group for Write handshake on failure. When my group fails, the error occurs. The values I’m attempting to write, however, are still going through … the tag is changing value as expected.
The tags in question are from a local OPC Server, (the same ABB OPC Server I’ve talked about previous conversations and threads).
