Analog signal in SC and to controller

RobotStudio
1

Hi,

I have an SC where I calculate a value representing a measured distance. My intention was/is to connect this value (Result from Expression) to an analog output in the SC and then connect that output to an analog input on the controller in the StationLogic.

I ended up with a couple of problems:

  1. The SC editor doesn’t allow me to connect the result from the expression to an analog output, but it’s okay to connect to a variable created in the Dynamic Property of the SC.
  2. In the StationLogic editor it is not possible to connect the variable in the Dynamic property of the SC to the analog input on the controller.

I also have some concerns with setting the parameters for the analog input on the controller. After some googling I found out that the Unit mapping should be set to a range of bits, I use 16-31 for 16-bit value. But how should I set up the fields from Maximum Logical Value?
I guess this is some kind of scaling function for engineering units but which field is the raw analog input and which is the measurement value? I haven’t found any examples on these settings.

you can find all the info you need on this in the:
