Hello everybody!

I Have some problem about the STL programming.

First i upload the program from CPU and i want to change the Input address from 2-Wire to 4-Wire 
After that i change the addressing at Hardware config it all done.

But in Scale Function that write in STL Programming that i have upload is seem to fixed the parameter. I cannot change anything  in this pointer such as Input Address, Hi and Low range. 

I try to edit symbol at the input address but after that the Address is back to the old address, Could you guy please explain what is the missing point that i did. 

In the Attached Picture. In the Left Panel is the scale block that i try to call and add the pointer parameter, but i got the error, but in the Right Panel is the backup block with same condition but its can compile complete.

This is the first time i interact with the STL Programming so im not have knowlwdge base about this. 

Thank you

Hello iceiceice,

I recommend inserting the program in a function block and using a separate instance DB for each function block (when called).

Call the scaling block again and re-parameterize it.

It could also be a timestamp conflict. As an alternative, there is the FAQ:

How do you update invalid block calls (time stamp conflicts) in calling blocks?
