RS-485 Modbus interface with DAQ and Labview

Thread Starter

Ms. Need help

I want to control an AC drive that has a RS-485 Modbus protocol interface. I want to hook it up to a data acquisition card from National Instruments and control it using LabView. Is that possible? Do I need any drivers or converters to interface them? Thanks a lot.
 
Hi,
Since it has a MODBUS protocol interface, you need a MODBUS Master driver in order to communicate with the MODBUS Slave available in AC drive. Check whether LabView has any MODBUS Master driver available. If not, you need to get one. Moreover since the physical comm medium is RS485, check whether the selected Data Acquisition card supports RS485 interface, if not you may have to get one converter too.

We are implementors of MODBUS protocol stacks, both Master and Slave. We do provide MODBUS drivers that can be used with any of the Data Acquisition and control systems.

For more details or assistance, feel free to contact me.

Cheers,
Santhosh

Sapia modbus active X works with National Instruments as long as you have one of the later versions of National's software. Get their driver and life is good.
