WSMBT is a powerful and simple to use .Net control that makes it easy to access data from a Modbus slave device connected to the PC's Ethernet network. Simply drop the control on your form and talk to your device with your VB.NET, C# or Managed C++.

Supported protocol variants:
Modbus TCP/IP
Modbus UDP/IP
Modbus RTU Over TCP/IP
Modbus ASCII Over TCP/IP

SUPPORTED MODBUS FUNCTIONS:
01: Read coil status
02: Read input status
03: Read holding registers
04: Read input registers
05: Force single coil
06: Preset single register
15: Force multiple coils
16: Preset multiple registers
17: Report Slave ID. (RTU/ASCII Over TCP/IP mode only)
22: Mask write register
23: Read/Write registers

Examples:

C#
Int16[] Registers = new Int16[10];
WSMBT.Result Result;
Result = wsmbtControl1.ReadHoldingRegisters(1, 0, 10, Registers);

Visual Basic
Dim Registers(10) As Short
Dim Result As WSMBT.Result
Result = WsmbtControl1.ReadHoldingRegisters(1, 0, 10, Registers)

C++
array<Int16>^ Registers = gcnew array<Int16>(10);
WSMBT::Result Result;
Result = wsmbtControl1->ReadHoldingRegisters(1, 0, 10, Registers);

User defined functions:
