4 - Functions
The scripts are stored in text form in the device, so there is no need for a compiler or other tools. If
you use the controller tool, it creates the script and uploads it to the device, so the device knows
what you want it to do.
Parameters are another kind of container for data, but unlike channels they can only be changed by
a user. They are used in scripts to specify conguration options and to inuence the script while it is
running.
