Siemens logo controller

Hello,
I'm trying to find out a little more infos about Siemens logo controller. I'm wondering how analog signals are represented. I know in S7 300/400 controller that analog value is represented in STEP 7 like integer between 0 and 27648. What is situation with logo?
Does anyone have any experience with it?
Thanks

You have to use the AI as analog input, and an analog comparator to trigger an action
