Human Machine Interface in-short referred as HMI, is a platform by which human beings can communicate with the machines. It consists of hardware and software which translates the user’s inputs to signals for machines.
Based on the input, the machine gives back the necessary result or output to the human being. It is applicable in various industries such as electronics, medical, military, automation, etc.
What are the benefits of HMI in the Automation industry?
- It helps in the enhancement of work:
HMI or Human-Computer interface is the key by which the company can reach all its targets. Particularly in the automation industry, it helps in the improvement of productivity and efficiency. Man power is reduced and more work can be done within a short period of time.
Because of this reason, many companies are adopting this technology.
- It sends signals if any trouble/s:
This machine even has got alarms present in it. By observing the alarms, the operator can find the malfunction and react to it swiftly.
Some alarms are of preventive type, which create a warning alarm when the hydraulic tank oil reaches an unfavorable point for instance. While historical alarm logging is effective to optimize process and keep a track of problems.
- Reasonable and just the best:
It helps a lot in trimming down the costs of hardware. A typical HMI can replace numerous push buttons, selectors, lights, etc.
Therefore, less number of consoles, panels and fewer cables will eventually help in the reasonable amount being spent all over the plant.
- Mind you, It even records your data:
Few know, but this interface can even record the data entered into it. When entering data, the related system around it records the data automatically.
As it keeps a record, all the data is used in future for troubleshooting mechanical problems, adjusting settings.
- OMG! It satisfies the personnel at work:
What can be more satisfactory than your employees satisfied at work? The workers in the automation industry can be at ease and much satisfied because of the HMI help.
According to a study, researchers have found that customers (online) have greater satisfaction when viewing websites on touchscreen rather when compared to a typical monitor.
- I help to improve communications:
No, no it doesn’t help humans in communication!!
HMI particularly helps in improving communications among a variety of equipment throughout the facility.
It improves communication with the help of remote I/O, Ethernet, serial port, Data Highway Plus, DDE (Dynamic Data Exchange) and other methods.
