Is it possible to change robot variables using RoboDK? 

I also need to communicate using Modbus. We use Techman robots. Thanks

If you are using the API, you can change the state of digital outputs using the setDO command. Depending on the robot controller, a certain digital output id can be mapped to a variable. For example, when you use TM robots you'll be wrtting this variable through modbus:

Code:

modbus_write("TCP_1", 0, "DO", 800+do_id, 1)
