I am looking for information on how to communicate with an Omega CN616A Temperature controller over MODBUS / RTU using LabVIEW. I have down loaded the Modbus Master, Plasmionique package. I have a USB to RS232 cable (COM 4). Omega provides an application that communicates with the CN616A device, and I am able to use this. I have tried different configurations in LabVIEW but I'm not able to read any data.
Note. The earlier CN616 module was able to use a serial port, but the CN616A is only ModBus.
