Service of HMI

Service of HMI

Service of HMI – There are numerous benefits to using a human machine interface and some of the most important ones are listed below as following.

  1. The machineries and procedures consist of very good quality of graphics so that all of the representations are realistically relatable.

Service of HMI – Due to this, the operator and the administration involved will be able to visualize a very real-like view of the plant. It becomes possible for the operator to handle all processes of the plant from one core location. This is also beneficial when security fears arise. Things are made easier for the operator as well who does not have to be in close proximity to the plant at all times in order to manage or monitor it.

  1. Both real-time and historical alarms data

Service of HMI – The operator of the interface can easily view alarms i.e. he or she can place and also respond quicker to any sort of malfunction or any anomaly. The alarms can be of different types, with one being the preventive type. This is the type in which a warning is generated for example when the oil level goes below a critical value in a hydraulic tank.

Historical alarm means that the alarms are logged and this is particularly useful when it comes to tracking of issues. It also contributes to the process optimization. And as a result of optimization, both the overall productivity and the total time lost are improved.

  1. Both real-time and historical trends

Service of HMI – Trends data comes in very handy in terms of PIDs. The curve made use of for the attainment of a specific set point can be easily visualized. This study of the set points and their attainment will help to optimize the whole process and increase the level of efficiency significantly.

  1. Recipe Manager

Both the simpler and complex recipes can be managed using HMI. The execution of recipes becomes much more effective.

  1. Simulation

There are some HMIs that are of such good quality that an operator can visualize a full-fledge simulation in just an office. This enables the PLC programmers to test their programs without even a single piece of plant equipment. This helps in significant reduction in the startup time.

  1. Messaging

The operator can message, page or fax any concerned person whenever there is the occurrence of a specific event. The animation and instrument depend on the standards of the operator.

The picture that will be generated is not just a picture but a complete animated picture. This will help significantly towards visualizing of the whole process and system. As a result, effectiveness and efficiency of anomaly detection will also be enhanced.

  1. Reduction in hardware expenses

The operator panel goes from countless buttons, selectors and lights etc. to just one human machine interface. This means that ultimately the hardware expenses are lessened as number of controls and cables minimizes.

  1. Communication

An extensive variety of human machine interfaces are able to communicate with a variety of the most typical and common PLCs. These communications include serial port, Ethernet, remote I/O, DDE etc.
