Activate STO with a button or scripting for MBL1660A driver controler

Good morning,

I am trying to implement a script that is activated when I press a button that I have connected to one of the driver inputs to send an STO. However, I have not found in the documentation how to make a script with this functionality or how to activate STO via scripting. If you could help me with this matter I would be very grateful.

All the best,

Enrique
