I would like to set a property on a context tag, say "PLCDriver", and it's value be "[PLCPORT01\PLANTPLC01]", which I can do.

In the children tags, that need to access the i/o, I'd like to use that value to get a driver.

If I enter \PLCDriver in the Edit Parameter Expression, it retrieves the value, but says --Missing--

If I select the same through the tag browser, it works as expected.

Or any other combination where I can "point" to the driver one time in the tag type instance once it is created.

Sorry if this is already documented or discussed, but I did not find it yet.

note: i haven't actually created a tag type from the structure yet to test, so I might do that also.

Thank you jcnaquin! I revisited that again, unfortunately had not any luck

For clarity, here is my tag structure:
\Root
---PLCPort01 (Port)
-------PLANTPLC01 (Driver)
---Templates
-------MyContext (With property "PLCDriver" = [PLCPort01\PLANTPLC01]
---------IO_1 (*I/O and Calculations)
---------IO_2

Expression in I/O Device in Tag IO_1
\PLCDriver =====> [PLCPort01\PLANTPLC01] --Missing--

\PLCDriver\Root =====> No Tag Selected

\PLCDriver\Driver =====> No Tag Selected

[PLCPort01\PLANTPLC01]\Root =====> WORKS!

Scope(Self, "PLCDriver" ) =====> [PLCPort01\PLANTPLC01] --Missing--

Can't find the right config to get the object while using a parent's property value.

Thanks for looking.

jcnaquin! That did it! Simply had to remove the square brackets from the parent's property.

So for clarity:
Parent Property: "PLCDriver" = PLCPort01\PLANTPLC01

AND
I/O Tag Expressioin for Driver:
\PLCDriver

Scope gets handled and actually don't even need \Root

Thank you again jcnaquin!
