There is an explanation how to use symbolic equations to generate an RoR curve in this Artisan Blog. Scroll down to 3.2 Computing Rate-of-Rise (RoR).

If you are using the Artisan Machine setup for Probat PIII the symbolic equation in the example must be modified to use "Y8", which is the symbol for the "Exhaust" value.
((Y8 - Y8[-1]) / (t - t[-1])) * 60

Go to Config>> Device>> Extra devices tab. Add a new Virtual device, label it "Exhaust RoR" under Label 2, paste the above equation under y2(x) and be sure LCD 2, Curve 2 and delta Axis 2 are ticked.
