Within minutes, your Excel, Access, Visual C , Visual Basic or other compatible application will be talking Modbus/RTU protocol. <br /> <br /> Any container application that can embed ActiveX controls can use SMRX. At design time, you can access your Modbus device from SMRX&#039;s test property page. This makes start-up and troubleshooting a snap, all without writing a single line of code! To further get you going quickly, SMRX also includes extensive online HTML help files with detailed examples for Excel, Visual Basic and Visual C .<br /> <br /> A powerful set of properties and methods are provided for configuring SMRX and for talking to slave devices at run-time. Talking to a Modbus/RTU slave is as simple as calling a function with the necessary arguments. SMRX automatically builds the command, appends a CRC, sends the command out the serial port, and receives and validates the response. Your program just reads and writes simple 16-bit data values. The example fragments below show just how easy it is to read the first ten holding registers from slave device 5.";
