ActiveX and .NET controls for Modbus TCP and RTU I/O modules

May 18, 2010
New ActiveX and .NET software tools simplify development of Visual Basic and Visual C++ applications to interface with Ethernet and Modbus I/O modules for industrial measurement and control systems.

Acromag has released a series of ActiveX and .NET controls to help engineers developing measurement and control systems in a Visual Basic or C++ environment communicate with their Ethernet and Modbus I/O modules. Acromag's AMRN/AMRX (for Modbus/RTU) and AMTN/AMTX (for Modbus/TCP) controls packages provide a fast, easy way to interface with any Modbus slave device (not just Acromag I/O) connected to a PC's serial or network ports. These software tools start at just $225. Free evaluation versions are available.Two software support packages are offered for Modbus/RTU and two for Modbus/TCP devices. The AMRX and AMTX packages are easy-to-use ActiveX controls that simplify communication with slave devices connected to a PC's wired or wireless network. They include a timer for polled data acquisition and a floating point conversion control. AMRN and AMTN are Windows Forms Controls (.NET) that provide a quick way to communicate with slave devices connected to a PC’s serial or Ethernet port.
