Question for our members: HMI Controller

Recommended Posts

Hello from Unitronics headquarters :)
Many of you probably know that Unitronics invented the OPLC: the Operating Panel + Programmable Logic Controller - which today, we call the PLC + HMI, or All-in-One controller.  

Recently, I've noticed that there seems to be a shift in terminology--the HMI controller.

Is this, in your experience, the more common term in use today?

I've got customers that can't grasp the concept of an All-in-one and simply refer to it as the HMI. I think the HMI Controller terminology would be something they could understand better.

For my customers it is simply just "the controller" as they don't interact with it much.  The panel is mostly always just for me. 

So....no relevant comment from Aus!

In my opinion, the HMI controller term slightly reduces the concept of the OPLC.
Now on the market, there are controllers (named HMI controller) that exclusively show on the big screen what PLC is doing now, however, they have nothing to do with the concept All in one.
I would use the term OPLC to explain students the difference between the classic HMI connected to PLC  and the concept All-in-One.

For me Virtual HMI controller is sutable for new Unitronics product (Unistream without real HMI).

I find myself saying "whatever, yes the TV screen, now tell me what is says" 😂 Not worth correcting people.

Sadly, all too common experience.

Interesting comments, thanks.
Among my other textual duties, here in UniLand, I write most of the marketing content.
After seeing HMI controller, I thought that might be how someone looking for a PLC + HMI might search for such a device....
