Quality Code of communications and data read by tag. The QCODE reports errors that occur while reading data from the automation device. 0 = good = no error. Any non-zero value is an error. Typically, a value of 8000 or greater is critical. The QCODE is displayed in the Point Info Dialog box for the tag. Typically, loss of communication will show QCODE as *  in the Point Info Dialog Box.
If "KEEP PREVIOUS VALUE" is NO, then an Asterisk (*) appears as the value of a tag indicating BAD DATA.
If "KEEP PREVIOUS VALUE" is YES, then the last good value appears as the value of a tag if communications fail. The QCODE is the indication of BAD DATA.
Refer to the specific Device Driver Manual for a description of Quality Codes for your device.
