MBAXP is a powerful and simple to use Modbus ActiveX control that allows Visual Basic, Excel and other OLE Container applications to quickly and easily access data from a Modbus slave device connected to the PC. MBAXP supports both RTU, ASCII modes and TCP/IP connections.
The communication in each instance of MBAXP runs in its own thread. That means: Your program does not stop responding while waiting for Modbus transactions to finish. You can communicate with multiple ports simultaneously.
