TwinCAT 3 how to show Visualization only

Hello Guys,

Let's say that i have Beckhoff IPC and a Panel PC , where they should work as follows

1) The IPC is where the engineering is done.

2) The IPC has OPC-UA licence and is connected to a panel-PC which is located far from the IPC , but both are in the same network and both have OPC-UA

3)The IPC will function as OPC-Server (engineer side) , the Panel-PC will function as OPC-Client (user side) ...and each one of them has its own visualization (by twincat plc)

everything is fine till now, the coding and everything is ok

The Problem:
---------------

the IPC is accepted to show the windows desktop and all other windows including twincat3 visual studio

but the panel-Pc should only show the output of twincat .. for example when i press "activate configuration" then "switch to run time" ---->> "log on" to plc , then the visualization starts to work , correct ? now i want ONLY the visualization to work on the panle-pc , i don't want any desktop ,any ability to "minimize , maximize open another exe" and so on. The user shouldn't even be able to see the coding ,correct?

i think this is what happens in the case of a machine HMI and also scada HMI , right?

How can i achieve this ?

thank you in advance

P.S: if the plc-visualization doesn't support such a thing , i can migrate all my buttons and other controls to c++or C# (exe)
 
Hi Karlek ,

I will check the link you posted , but Is the user able to do any of these:
a) press alt + tab
b) press alt + ctrl + delete
c) call task manager
d) press minimize (if existed)
and so on

If the user can't ( i.e , forced to that screen ONLY ) then that is the answer to my question

so , could he ?

about your question : in general , yes ...but Panel-pc has higher CPU specs than control panels ( core i7 , RAM , etc) and the client side may run other modules by calling them through the HMI , so not only visualization , in general we are still studying this (display only or panel-pc)

Thank you a lot , and I will let you know if the above link is what i am seeking

There is definitely no minimize button once the visualization is started (you only see visualization screen you created in TwinCAT 3).

As for your other questions (Alt + Tab, etc.) I am not 100% sure because I used Twincat PLC HMI on Panel PC with Windows CE operating system and I don't even know if these key combinations exist on Windows CE (no Task manager in Win CE).

Very well , the statement you wrote "no Task manager in Win CE" just solved the questions in my mind , the os of the IPC we are targeting from Beckhoff is Windows 10 IoT enterprise . This link answers everything

Thank you karlek , you answered my question
