Parameters

• tagId
  ID of the tag whose user data it is writing to.

• userData
  User data to be written.

• start
  Indicates the zero-based position within the tags userData field to begin writing to.

• timeout
  Allowed execution time, in milliseconds, before the method fails and a timeout ErrorEvent is sent to the application. If WaitForever, the service will wait as long as needed until either the operation is complete or an error occurs.

• password
  Authorized key for reader that might be required for this operation, null if not applicable.

Remarks

Application should query the CapWriteTag property for this operation’s supportability.

This method is always performed asynchronously and the OutputId property will be set on a successful start plus an OutputCompleteEvent event or an ErrorEvent event is raised to indicate completion.
