Hi everyone

Is it possible to create a custom user login frame with simple text fields for username and password and a login button that executes the search for a matching user name and password? Basically I want to use the existing backend of the stock user management but not the front end graphics. The reason for this is that I am having performance issues using the on-screen keyboard that is built into the front end of the stock user management. I don't have any performance issues if I use a simple text box and pop-up keyboard. It's strange, but this should help get rid of the lag I am experiencing.

Thanks in advance

I can say that the same behavior is observed on both Eaton's XV100 and XV300 machines with respect to the slow login screen behaviour. The XV100 is the worst of the 2, being much older hardware, taking several seconds per button press using the login dialogue's on-screen keyboard. It's a problem they've acknowledged before but one without a solution. It can even be a problem when using a webvisu provided by an XV100. All they recommend is using their suggested visualization style or switching to using 1 of their visualization software products like Visual Designer or Galileo. It is also a hardware issue from what tech support has told me. I don't experience the same problems when using either of their products.

It would be nice to have an example project on the Codesys Examples page that demonstrates what dgirard would like to do. Also which demonstrates how to login a user programmaticly. Like if they use an RFID card or use a locked switch to login.

I say that but here is a post with a project demonstrating changing the logged in user via IEC code. It's just not as easy for someone to find. It does seem to be a question that pops up occasionally. You might find something that helps you in there @dgirard

Thanks @Morberis, the example on the pi page was very helpful and has me headed in the right direction.

One question for yous: the code snip below will log me in automatically, but regardless of which visualization I log in from, it will always log me into the TargetVisu. Do you know what is missing so that it will log me into the visualization from which the login button was pressed? I'm assuming it has to do with detecting the press of the button and matching it to the proper pclient?

LoginButton_R_TRIG(clk := LoginButton);
BooleanTest := TRUE;
IF BooleanTest THEN
        VisuElems.g_ClientManager.BeginIteration(); 
        pClient := VisuElems.g_ClientManager.GetNextClient(); 

        WHILE pClient <> VisuElems.NULL DO 
            IF (pClient^.GlobalData.CurrentUserGroupId <> 3) THEN 
                arr[0] := 3; 
                arr[1] := 3; 
                IF LoginButton_R_TRIG.Q HEN
                    VisuUserManagement.g_VisuUserMgmt2.LoginToUserGroups(pClient, ADR(arr), 3, STRING_TO_WSTRING(username), "Operator"); 
                END_IF  
            END_IF 

        pClient := VisuElems.g_ClientManager.GetNextClient();

        END_WHILE
END_IF

Thanks in advance!

Hmm so if you login in 1 client it logs in on all the visualization clients? Do you get the same behavior if you use the normal login dialogues? And are all the visualization clients locked into viewing the same pages or can they all look at a different page?

I remember something about this but I'm sorry I can't seem to find any good info.

I did find this page, Using Events of the User Management (Login/Logout)

You might find an answer in the Client Independent Visualization Switching example project.

I also found this post which is of dubious help here.

Someone else has asked this before. I'm sorry I can't seem to find anything in the time I have available though.

Thanks for the resources!

No, it only logs me into the TargetVisu, none of my Webvisu will get logged in even if I am pressing the login button on the Webvisu Visualization.

I need a way to detect which client has pressed the button and log in that specific client. Any idea how to achieve this?

which version are you using?

V3.5 SP15

maybe worth to check with current version.. if possible.

The problem is that you are iterating over all clients with your ST Code and log in every client.

First of all you should never iterate over all clients with this function outside of the visu task. If you have to iterate, use VisuUtils.

Secondly, you can get the current client in the mouse click action.
Call a function in your input action and include the argument pClientData.

Best regards,
Marcel

@m.prestel thank you for the info.

I have got it mostly working now. The only thing remaining is retrieving the FullUserName from the internal user database. Does anyone know a command or method for that? I can't seem to find anything for this, but I would expect there to be a method that could return this similar to VisuUserManagement.g_VisuUserMgmt2.CheckLogin().

Here is what is working so far: (please note that so long as the username and fullusername are the same, this code works fine)

pclient2 := VisuElems.VisuElemBase.g_ClientManager.GetClientData(pClient2ID); //pClient2ID comes from button on Visualization
LoginButton_R_TRIG(clk := LoginButton);
arr[0] := 3; 
arr[1] := 3; 
IF LoginButton_R_TRIG.Q THEN
    LoginOK := VisuUserManagement.g_VisuUserMgmt2.CheckLogin(STRING_TO_WSTRING(username), STRING_TO_WSTRING(password)); //check for valid username and password
    IF LoginOK = VisuUserManagement.VUM_ReturnValues.ERR_OK THEN 
        VisuUserManagement.g_VisuUserMgmt2.LoginToUserGroups(pClient2, ADR(arr), 3, STRING_TO_WSTRING(username), STRING_TO_WSTRING(username)); //login the user
        LoginMessage:= 'LOGIN SUCCESFUL';
    ELSIF LoginOK = VisuUserManagement.VUM_ReturnValues.ERR_VUM_USER_DOES_NOT_EXIST THEN
        LoginMessage:= 'INVALID USERNAME';
    ELSIF LoginOK = VisuUserManagement.VUM_ReturnValues.ERR_VUM_WRONG_PASSWORD THEN
        LoginMessage:= 'INVALID PASSWORD';
    END_IF                  
END_IF
