Tag Status

The Tag Status element is used to represent the current status of the tag. The value of this element is affected only for those tag operations that involve a physical device (for example, writing to the Field element will affect the status element, but writing to the Control Mode will not). Tag Status element is reset after I/O Server restart. The element value contains a set of bit flags.
