I have created a OPC connection -OPC-DA COM Connection for a Micrologix1500. Status Connected. In Ignition, the added OPC connection appears no problem, including all the Tags on my Micrologix PLC. Although as i drag the OPC Tag into the Tags section, Firstly the Quality States: Uncertain\_InitalValue, sometimes it comes up Bad\_NotConnected.  
Any help apprieciated,  
Thanks.
