Resolver problem

nothing... (normally).

(there is a longer explanation but for that please consider Kuka training).

if you see empty string as a result and there is no message about missing object, you are using correct name, variable is declared, but not initialized (there is nothing updating the variable). are you sure you activated fast measure inputs in WoV? did you deploy and activate the project after that?

it is under Additional Controller Settings, Enable Fast measurechannels

if the configuration is correct (even without X33 interface installed in the cabinet), you should be able to to monitor high speed inputs with single variable monitor
