There are fields available in Object Viewer that allow you to verify if an attempted write value successfully updated an I/O attribute value in Application Server. This article explains what those fields are and how to use them.

The image below shows a list of items used to see if a value was written to an attribute. The table beneath the image provides more detail. 

The sample I/O attribute used is W_Setpoint.





If .WriteStatus indicates a successful write and .WriteValue and .WSetpoint are equal then you know that the value was successfully written.
