How can I connect a temperature controller RS-485 with a DAQ?

[Claycar]

I have a problem, I need connect a temperature controller with LabVIEW but my problem is how because I need read temperature and time of the controller Yudian AI-518 and send it set points too. I don't know how it is possible because Yudian doesn't give me a driver for LabVIEW.

RS485 is a communication bus. You need a USB to RS485 module to communicate from LabVIEW via VISA with the instrument.

Maybe you can also control this instrument via DAQ because i has analog inputs and outputs but I would go for the RS485 bus. In fact it is a MODbus device.

You can find the commands to send in the pdf as a visual basic example at the very end of 

AIBUS/MODBUS protocol.pdf

If you have not yet programmed in LabVIEW I would seek help from somebody who has.

I tried the communication for VISA but I can't initialize the device. I don't have knowledge about develop drivers for devices, If you can help me about initialize a device like Yudian AI518 and can receive data and send it set points.

Hello Claycar,

In this link you can find options to communicate with your device.

Besides in LabVIEW you can go to Help>>Find Examples>>Visa, and you will find some examples that may be helpful.

Best regards.
