Control Technology Corporation (CTC) has developed a reliable, web-based controller software package for automation activities called “WebHMI“. This software package will provide the user with a real-time, interactive, graphical interface for the access and control of automation activities within the browser environment of today.
CTC WebHMI offers a variety of features in this product for the automation industry. CTC provides the user with a variety of interactive panel media (i.e. switches, dials, displays, and etc.) at various sizes to remotely view and adjust automation activities from any workstation through the Internet. The interactive WebHMI panel media are created with CTC’s HMIBuilder software and developed into webpages on an embedded webserver, such as the company’s Blue Fusion 5100 series controller. CTC WebHMI will then allow the user to access the webpage from an Internet or Ethernet connection. CTC does require the user to have version 5 or later of Internet Explorer and Java Virtual Machine (JVM) version 1.4.2 for the WebHMI pages. The proper versions of these required programs are available at no charge to the user from CTC’s website. Adjustable security levels are included in WebHMI to maintain the stability of the user’s automation processes. The CTC website offers specific software information and downloads in the site’s support tab.
Human Machine Interface (HMI) is part of the Supervisory Control And Data Acquisition (SCADA) system. SCADA is described as a macro-scale system to monitor and control automation processes, and recognized as a link in the engineering of industrial instrumentation. HMI is the actual means in which the user accesses and controls the automation processes through a Programmable Logic Controller (PLC) or other such device over some form of network, which presents process data to the user. Some HMI packages offer the option to be linked to a database that provides other detailed information (i.e. device schematics, diagnostic and/or management information, etc.) to further enhance automation processes for the user. HMI/SCADA products have been used by a variety of engineers and technicians because of its simple implementation and reliability qualities.
Control Technology Corporation is headquartered in Hopkinton, Massachusetts with offices in Wisconsin, Michigan, and California. CTC is a premier designer and manufacturer of products that access and control automation process. CTC was founded in 1975, provides automation solutions to a wide customer base for over 30 years. CTC has maintained expertise in digital and analog circuit design, language technology, control software engineering, and other aspects for the automation industry.
