The Interface Between Process and Operators

The Human Machine Interface (HMI) is the interface between the process and the operators – in essence an operator’s dashboard. This is the primary tool by which operators and line supervisors coordinate and control the industrial and manufacturing processes in the plant. HMIs serve to translate complex process variables into usable and actionable information.

Displaying near real-time operational information is the domain of the HMI. Visual process graphics give meaning and context to motor and valve status, tank levels and other process parameters. HMIs give operational insight into the process and enable control and optimization by regulating production and process targets.

Traditional HMI Control Systems

inadvertently creating situations of information overload

Exacerbating this problem is the fact that there is a general scarcity and shortage of skilled labor and expertise to understand all this information. Furthermore, operators’ responsibility is often enormous, their shifts are too long and they are prone to fatigue. With this problem growing in intensity each year, the need for ease-of use has never been greater.

Wonderware’s unique approach enables operational efficiency

First, modern HMIs must automatically focus the operator’s attention on the problem. They must enforce standard operating procedures and ensure timely, easy identification of abnormal conditions. Advanced situational awareness design must help the operator see what is happening, focus on the problem and deliver relevant screens instantly.

Secondly, modern HMIs must be aimed at more than process visualization. They must connect people, applications and machines for greater collaboration, efficiency and economy. The HMI must expose the relevant information, to the appropriate people, at the right time; enabling them to make better decisions.
