I am developing software in visual basic for communication of one PC with temperature controllers. I need one driver modbus for visual basic.

 

Please check out either SMRX or SMRL at http://www.sapia-inc.com. These are Modbus/RTU Master ActiveX and Win32 dll respectively. Either one will work with VB6. You can download a fully functioning demo and have your VB app talking Modbus/RTU within minutes. Hope this helps.

SoftwareToolbox.COM has an ActiveX that you can drop in VB to do this.

 

Check out Automated Solutions website (http://www.automatedsolutions.com) for a complete line of Modbus Master and Slave ActiveX Controls.

Fully functioning evaluation versions are available for download and the included pre-built applications will have you communicating with your Modbus devices in seconds.
