Change conveyor speed with robot signal

Hi guys, just wondering if there is a way to change the speed of the conveyor using a GO signal from the robot. Our real robot sends a GO from 0 to 100 to the PLC which uses this value to adjust the inverter for the conveyor. It would be useful if we could do the same with a smart component but I can.t really see anyway of doing it…
We currently just type in the speed depending on the product we’re running in RS at the time…

Cheers
Neil.
