How to get data from multiple devices like smoke meter,plc controller,etc to my application which contains lots of forms

I am currently using a software where i have to measure speed,fuel efficiency,torque,etc. This values will be obtained from controllers and other measuring devices.Actually my software is successfully communicating with all this devices. I have multiple forms in my software/application and multiple devices for getting data.Each device has a list of parameters to be measured.Is it possible to get all this lists in a single class and use them for different functions like calculations on 1st form ,display data on 2nd form and real graph on another form? And my second problem is if i have changed data in 1st form it should be reflect on all other forms at same instance?
