I want to establish serial communication between Jetson nano and a Velacio PLC.
The Velacio(in this case) is used to control stepper motors in this case and I would need the feedback of the position of the motors.
Pins 8,10 on the J41 header for serial communication and J50 automation header are already used up.
I was wondering if it is possible to establish communication via USB to RS485 or even USB to RS232 convertors?
The Velacio PLC also supports Modbus RTU protocol and can be setup easily via s/w as shown below.
