How to Choose HMI Panel to Apply to Control Panel
Navigasi - when we manufacture or assemble a control panel for an industrial machine, we sometimes find it a little difficult to install all the control tools (spare parts) on the panel such as push buttons, emergency buttons, selector switches, and other components that take up a lot of space on the panel we are currently working on. wiring.
This is a concern for scientists and companies that develop components / spare parts for assembling Industrial Machinery panels so that they create an electrical panel control device with a touchscreen system called HMI (Human Machine Interface).
Understanding HMI (Human Machine Interface)
HMI is an electrical control panel device that functions to connect the machine system to humans so that they can operate the machine and can control the industrial machine system.
In general, HMI is an industrial machine control computer with a CRT or LCD monitor screen display and we can see the machine control system, operate the machine and also make adjustments simply by touch (touchscreen).
In the industrial world itself, HMI is not only for operating machines and setting industrial machines, but by using HMI we can also monitor the working data of the machine system easily and more accurately if we compare it with conventional or manual methods.
In addition, HMI is easy to use by anyone and is very easy to program and is resistant to industrial environmental conditions.
HMI itself has many advantages and benefits so that it becomes a technological breakthrough in the industrial world for its functions that you have not or that you already know you can read in the following summary:
level limit of the component.
For example, we can set the RPM limit of an electric motor by setting the full speed and the lowest speed (high priority and low priority).
We can add a safety alarm system to the machine by using HMI.
Because the HMI has been equipped with an Alarm History and summary so that we can make security settings by activating the security alarm contained in the HMI if the machine takes actions that can make the alarm work, the HMI can trip or turn off the machine automatically.
And also if the engine alarm is active we will get a notification or message on what alarm HMI system is active and causes the trip so that doing the engine control system is much easier.
HMI working system
The HMI itself will be connected to a PLC to activate all the systems contained in the HMI by entering the program with a computer or laptop.
No wonder the company that produces HMI definitely produces PLC as well. For more details about PLC you can read the article below:
|Programming HMI and PLC|
So we need software and also programs that have been installed on a PC (computer or laptop) usually the software is the same as the PLC brand and also the HMI that we will install.
Then connect the PLC and HMI with the data cable, don't forget to also connect our PC to both (PLC and HMI) also with the data cable then install the program that we have made to the PLC and HMI via our PC if it is PLC and HMI will be connected and can operated.
is definitely much cheaper if we compare it to the full color one.
What screen resolution is required to display sufficient detail of graphic objects or to support viewing multiple objects on the same screen?
How about installation? Should the HMI be mounted on the panel? Or on a pedestal? Or be Handheld?
What type of protection does the HMI need? IP67 to protect against liquid splash or outdoor installation?
What interface do I system? Ethernet ? Profinet? Serial interface for laboratory instruments, RFI scanners or barcode readers? And do I need some kind of interface?
What are my software requirements? Do I need an OPC or special driver to access data from my controller?
Do I need to run custom programs in the HMI terminal to support factory operations, such as barcode software or inventory application interfaces?
Does the HMI need to support Windows and its file system, or is the vendor's HMI application sufficient?
These things are a consideration for you in choosing the HMI to be installed on the electrical panel that you will install.
