Modbus TCP systems: Visualizing modern, flexible and economically over the web



  • Brings your Modbus TCP-networked automation equipment to the web
  • Enables platform neutral and free of charge visualization over all common browsers
  • Lets you monitor and operate your machinery from any mobile anytime, anywhere
  • Comes with touchscreen-ready controls and gadgets for fast implementation without programming

Product Description

The Web-HMI Server brings your Modbus TCP-networked automation equipment and industrial manufacturing systems to the web. The device links to the targeted system with the vendor-neutral Modbus TCP/IP protocol as client or server. The integrated 2-port Ethernet switch on the underside connects the device IT-friendly to the existing LAN network. The independent third port Ethernet on the front connects to the Modbus TCP network.

The web visualization is managing the pages without plugins such as ActiveX®, Flash® or Java®. It can be executed by all leading web browsers. The interface scales automatically and adjusts to work on any web browser enabled device from a Smartphone all the way up to a web-enabled High-definition television. The simultaneous access of multiple browsers at a time is also supported.

Although native web technology is being used no HTML code programming necessary. Front end creation as well as the dynamizations of the visualizing controls and gadgets are easily and quickly configured with a few mouse clicks. The Modbus values as basis are defined as tags in a symbol editor and just applied to the controls afterwards. Color change, movement, scaling, user rights, the support of all common graphic formats and multilingualism are possible. Online data monitoring, alarming/acknowledgment and data trending are supported. For best visual effects a large catalogue of high-quality graphics from the industrial sector is available as library on demand.
