How to Turn on Logging Mode

I tried setting my analog input device object to log some data, but I ran into these errors.

I think I fixed it by putting quotation marks around Disk, but I have some questions. What exactly do quotations do in MatLab? Why does Logging need to be on? I seem to be able to run functions like peekdata or get sample with no problems.

quotation marks indicate strings.

Logging is not mandatory. Logging is for the case where you want to be able to analyze the measurements later, and is not required if you are able to deal with the measurements in real-time.
