I need to address a tag in a ControlLogix PLC which only has the channel and device specified.
The channel is CPU10101, and the device is PLC.
The tag I’m trying to get to is in the MainTask, Program SUM_Comm, Tag SUM01_RIO_Fault. The tag is BOOL, and created as a Public Parameter, with Read/Write external access.
When I specify the OPC Item Path as “ns=2;s=CPU10101.PLC.SUM_Comm.SUM01_RIO_Fault” I get Bad for the value with the following popup:
Show your actual code.
I don’t think that your Item Path is correct. I believe that it should be:
ns=2;s=CPU10101.PLC.Program:SUM_Comm.SUM01_RIO_Fault
I could be wrong though, as I refuse to use Kepware to connect to a device that Igniton can connect to naitively
What DataType did you specify for the Ignition tag? If you browse KSE and drag this tag from the OPC Browser to the Tag Browser what’s different?
That did the trick. Thank you!
