fDesc[0] = "SMRN is an easy to use Modbus/RTU Master Windows Forms control that provides a fast, convenient way to communicate with Modbus/RTU slave devices connected to your PC&#039;s serial port. Within minutes, your VB.NET, C# or Managed C application can be talking Modbus/RTU. <br /> <br /> Talking to a Modbus/RTU slave is as simple as calling a function with the necessary arguments. SMRN automatically builds and sends the request over the network, and receives and validates the response. Your application just operates on simple 16-bit data values representing Modbus registers, coils and discretes.<br /> <br /> SMRN can be used on a form as shown below, or optionally without a form. At design time, you can access your Modbus device from SMRN&#039;s built-in Test Panel. This makes start-up and troubleshooting a snap, all without writing a single line of code! To further get you going quickly, SMRN also includes an extensive HTML help file and example projects for VB.NET, C#.NET and C .NET. <br /> <br /> A powerful set of properties and methods are provided for configuring SMRN and for talking to slave devices at run-time. The example fragments below show just how easy it is to read holding registers from a Modbus/RTU slave.<br /> <br /> For Modbus devices that use floating point data, SMRN provides RegsToFloat( ) and FloatToRegs( ) conversion methods to handle the job. These two methods convert two consecutive Input Registers or Holding Registers into a 32-bit, IEEE single precision floating point number, and vice-versa respectively. <br /> <br /> Main features:<br /> -Send Custom User Request - provides unlimited Modbus functionality<br /> -Access Raw Request/Response Frames - helpful for troubleshooting<br /> -Built-in IEEE Single Precision Floating Point Support<br /> -Visual Indication of Communications - Comm. LED<br /> -Visual Connection Status<br /> -Built-in Test Panel - powerful troubleshooting aide<br /> -Can be used on a form (Visual Programming) or without a form<br /> -Low-level serial I/O primitives for non-Modbus reading and writing";
