Rustine (Customer) asked a question.
Hi everybody,
so a while back I faced a strange bug while coding my PLC. I had a UDS variable called Inputs that was from another UDS type (robot_inputs).
It happened with PS 3.8.0.14. I'm running now PS 3.9.0.26
One day the type was changed from the UDS type Robot_inputs to simply boolean. I have no idea how it happened as if I try to change a variable that is already used the software just wont let me do it.
So I had to create a new variable (inputs2) of the right original UDS type and replace every single occurence of the old variable (inputs).
Now as you can see in the picture below the Tag Database and the UDS definitions does not show anymore this variable Inputs. but for some mysterious reasons it is still showing up in the ladder.and I can set a contact with this ghost variable.
I can't find a way to get rid of it. I tried to export the UDS database to a csv file but the data is encoded.
any ideas?
thank you
Can't duplicate this issue by creating the same UDS structure and using it in ladder.
I would recommend filling out contact support form & attaching an online system report so we can try and duplicate on our end.
Exactly, I tried for days to replicate the error but I just can't.
