What you have to Consider when choosing the right Human Machine Interface

1. What you have to Consider when choosing the right Human Machine Interface Today, technology and engineering rely greatly on interconnections – the internet of things. Therefore, the growth and sophistication of the internet of things will directly influence the way humans interact with devices in that there will be the need for more modernized interfaces for control these devices. In order to ensure proper functionality and operation of these devices, you opt to choose the right HMI system. So, what is HMI and how can you ensure that you choose the right one? What is HMI?

2. HMI is the abbreviation for Human Machine Interface, and it is the platform through which end users interact with and monitor process controllers. Basically, HMI systems translate complex data into information that can be understood by human operators. This kind of information helps the end user control and manage each and every manufacturing and industrial processes within a particular plant. The information provided by HMI is very crucial in that the end user depends on it when providing feedback about the state of an industrial process. The end user will, therefore, be reassured that every automated process is running smoothly and they adhere to the set parameters. HMI systems may provide inputs through avisual display or even through audio feedbacks and alarms. However, there is HMI SCADA that combines multiple functionalities in one system. Human Machine Interface does not only provide output but also allows for inputs in form of push buttons, dials,andtouch-screen displays – in modernized HMI systems. These inputs are used for control as they provide a means for initiating, stopping, adjusting or programming processes. Factors to consider when choosing an HMI Human Machine Interfaces is very important in an automated industrial process, however, choosing the right one can be very difficult as it requires analysis, accuracy and sticking to the context of use. Here are some of the factors you may consider when choosing an HMI. The operating environment – this is one of the key consideration. Operating environments can either widen or narrow your choice of an HMI. For example, if the HMI is going to be used in a noisy or environment full of vibrations then you will be forced to choose a one with a hardened panel.

3. Present and future application– may are times that industry will change its system requirements and need hence the right HMI should have the ability to adapt to these changes. What the HMI will be connected to – Your choice will fully depend on the subsystems with the system. You should be able to answer questions such as, what are modes of connection in the system – USB or Ethernet? Does the system have only one PLC or multiple? The data entry tool that suits you best – Most HMI systems provide two modes of data entry – touch-screen and keypad. Here you have to consider the preferences of the end user. Also the need or relevance one data entry tool may change according to situations i.e. when it comes to entering large chunks of numerical data the keypad may be suitable. These are just but a few factors that you should keep in mind when choosing a Human Machine interface.
