Tag value show bad

Bad("Bad_NotConnected: The variable should receive its value from another variable.")
error .How can I solve it? Currently I am testing my DVP16ES2 plc with ignition opc ua server.The device is connected.But I cannot create any tags.I use the Delta DVP series plc modbus addresses.


Go to View -> Panels -> OPC Browser. Then, find this device in the Ignition OPC-UA Server -> Devices. Are you able to see the tag(s) in there?

IA's modbus driver only shows items from the mapping table in the OPC Browser. If the mappings are broken, the display tags will be broken as well.

Test with actual tags with manual addressing.

(Or use my alternate driver, with does show possible non-mapped addresses in both OPC browser and in the web quick client.)

Yeah .I can see tags in there.

Now it shows access level does not allow writing to this node.

The first screenshot makes me think that you're doing something wrong somewhere.
Can you show us what raises that error ?
