Why would someone choose to pay for the exorbitant expense of an HMI when they could just use push buttons or nothing at all instead? A portion of this is determined by how you plan to operate the apparatus, a portion is determined by whether or not you need to collect or use data, and the remaining portion is determined by how quickly you would like to troubleshoot a simple or complex system. Let's take a deeper look.
Let's simply simplify it down to basics rather than going into all the technical details. Do you even require an HMI display in the USA, and if so, which kind would be best for your equipment?
Why you need an HMI:
You will need to configure unique settings for each component, item, or substance that you are processing. You will also need to run specific pieces of equipment manually in order to perform manual maintenance.
Need to trend particular data values to keep an eye on quality, speed, number, or other areas of interest Need to examine all of the components in the system from an overview display and identify irregularities.
Do you need to make specific adjustments to the timing settings?
It is necessary to quickly troubleshoot complex systems in order to restore normal operation.
Few of the top HMI displays in the USA:
If your system does not actually require any of the aforementioned components, then a more fundamental form of operator control may serve as an acceptable replacement for the pushbuttons and pilot lights. In that case, the following is some background information about the various models
Panelview 800
The Panelview 800 provides a fundamental graphic user interface. The graphics are always displayed at the same resolution. When the screen size is changed, the objects do not scale very well. Interfaces quickly and easily to Micro800 PLCs, which makes it a good HMI display in the USA.
The software used to program the PLC logic can also be used to program graphics. As a result of the shared software interface, tags may be fed into the HMI visuals from the PLC logic with relative ease. Restricted access to supplementary features such as the reading of PDFs, data logging, network connectivity, and remote troubleshooting, among others.
A company's brand identity is the combination of visual and content choices that represent your company's personality. It's the face of your brand.
The navigation system needs to be built from the ground up. A restricted number of visual objects with multiple uses. When beginning from scratch, the programmer uses a blank canvas. Memory constraints. Less expensive.
Panelview Plus 7
One of the top HMI displays in the USA is Panelview Plus 7 which has an advanced graphical user interface. The same resolution is always used to show the graphics. When you change the size of the screen, the objects don't fit very well. It is easy to connect to the CompactLogix system.
Visual programming software is different from PLC logic programming software (requires the purchase of a separate license as well).
The navigation system has to be made from scratch. There is no way to manage users right out of the box. Great graphic pieces that can be used again and again. Some things don't have all of the features (like animating a push button). A programmer starts from scratch with a "blank canvas." A large amount of RAM is available, making it the best HMI display in the USA.
Panelview 5000
Panelview 5000 is slated to succeed at some point in the future. Preparedness with PlantPAx and the Machine Builder Library (premade programming code offered from Rockwell Automation online for free).
The resolution of graphics can be adjusted. When adjusting the size of the screen, things scale well. Simple interfaces to CompactLogix, complete with live error detection and debugging.
The navigation system is built in and very simple to configure. Excellent graphic pieces that can be reused. On practically any object, you can access any and all of its attributes. A solid repository of various things. A substantial quantity of RAM is available. Preparedness of the Machine Builder Library (premade programming code offered from Rockwell Automation online for free). More Expensive.
Choosing the best HMI Display in the US
To put it another way, that significantly simplifies things. If you delve deeper into the technical specifications, there are other factors to take into consideration. But for the time being, this will help with making a decision regarding an HMI more quickly.
