Quality bits are received in the Quality property of each Tag variable. The Quality property follows OPC DA specification and contains a fixed byte mapping, QQSSSSLL, where QQ means mapped to good, invalid, reserved, and questionable bits in the order Good, Bad, Bad, and Uncertain OPC values, SSSS means maps all other bits, and LL means not mapped.

Quality codes are carried together with their timestamp and value and can be configured as a Link to any object in E3 or Elipse Power.
