Addressing bits with OPC - UA

[c.bertulli]

Hi All,

I need to access a single bit from an int OPC Tag. From what I know you just have to add a .# and change the Tag’s datatype to boolean. That’s exactly what I’m doing, but is not working. The tag says “Bad Quality”.
FYI:
-I’m using Ignition 7.9.10
-I have no device configurated since I’m using KEPServer with OPC - UA
-The PLC is a Logix ( CompactLogix / ControlLogix )

In expression language you can use getbit() function…https://docs.inductiveautomation.com/display/DOC79/getBit
In scripting… http://forum.inductiveautomation.com/t/getbit-equivalent-for-use-in-a-client-event-script/15538

Also… searching forum for just getbit gives plenty results… http://forum.inductiveautomation.com/search?q=getbit
