The integrated Web Visualization of netSCADA Modbus sets the path of graphical Web Browser based HMI for low cost control of automated machines and industrial manufacturing systems. The device links to the targeted system with simple Modbus RTU protocol over a serial RS-232, RS-485 or RS-485 connection. The two Ethernet ports with integrated 2-port switch functionality are connecting the unit economically with the existing network at no need for additional Ethernet Switches.

The Web Visualization is managing the pages without plugins such as ActiveX®, Flash®, Java® or Silverlight™ and can be executed by all leading Web Browsers. Visualizations can be displayed and accessed on any Windows®/ Linux PC based system as well as such on tablets and smartphones with browser support. The simultaneous access of multiple browsers at a time is also supported.

Although native Web Technology is being used there is no HTML code programming necessary. Front end creation as well as the dynamizations of the visualizing elements are easily and quickly configured with a few mouse clicks. Color change, movement, scaling, user rights, the support of all common graphic formats and multilingualism are standard. Next to monitoring online data, Alarming and Acknowledgment and Data Trending are supported. For best visual effects a large catalogue of high-quality graphics from the industrial sector is optionally available as library.
