PCSDK Exception when accessing IOSignal

Hi,
I got following exception when trying to get Signal unit. Any ideas of cause or how to fix this?
Using 6.05. The controller is connected (connected to virtual controller running on RS)
if I comment this line everything else works great. So signal object itself is OK.

  • Hi Mika,

    What version of RW are you using?

    The error code received by the RobAPI-call literally means "Invalid attribute name" i.e. this instance does not have an attribute by that name. The error code seems to be correctly mapped by the RobAPI-code, so I don't know why RS thinks this is an "Unknown error".
