Hello,
I have a system with a pump whose control interface is RS485 db15 (2 wires). I have connected a USB to RS485 adapter, which I plugged into my computer (see attached picture).
I want to be able to control the start and stop of my pump with Labview.
Do I have to use the Modbus protocol or can I use VISA directly? How do I go about it? I am new to Labview.
Thank you in advance for your answers.
