Available options for the WriteFeedbackMode property
Option |
Description |
|---|---|

NOTES |
•OPC UA Driver's WriteFeedbackMode property cannot be changed with the object still active. •In option 2 - wfTrustWriteSuccess, for asynchronous writings, the value is assumed in the Tag after scheduling a writing, if the operation is successful. However, if that writing fails later, the Tag's value may be wrong. For synchronous writings, the value is assumed right after the writing finishes, if successful. |
