Using Modbus with Visual Basic 6.0

Thread Starter

I would like to develop a VB GUI for a Wago 750-315 I/O coupler. This coupler uses the Modbus protocol over a 485 line. I have zero experience with the Modbus protocol, are there Active X components available to assist with Modbus? Any suggestions or links for using VB with Modbus?

Any help would be greatly appreciated.
 
WAGO used to have a DLL that they offered for free that will work for VB to talk Modbus RTU or Modbus TCP.
 
Hi,

Modbus Active X and DLL's are available which could be interfaced with any of the VB or VC++ application. I can help you in this regard if you are interested in developing one of your own.

Cheers,
Santhosh
