I am trying to read Siemens PLC S1200 tag , I create device first, it shows connected .
Then I go to Ignition designer, create OPC tags as below :
It shows bad.
Below is screenshot from my Siemens Portal software.
I tried to revise my OpcItemPath from [Test_1200]IW96 to II96 , same issue.
Where I did wrong.
Did you follow the four instructions in the manual titled "Considerations for 1200 and 1500 Devices" ?
May I ask where to configure this, is this in Siemens Portal software ？
Forgive me , I am not familar with PLC coding, it's done by another guy.
The acces level and connection mechanism are under Protection and safety.
Look here...
