LabVIEW Modbus

‎08-03-2023 11:29 AM - edited ‎08-03-2023 11:30 AM

I need to communicate with an instrument with LabVIEW through MODBUS using RS-232. 

The instrument is the slave and the computer is the master. 

I'm using the NI MODBUS Library 

Question: when creating a MODBUS instance in labview should it be NEW Serial Master or New Serial Slave ?

The computer should be a New Serial Master since you are simulating a master on your computer to communicate with the slave instrument.
