Hi and thank you for your answer.
I had already seen this example.
But i don’t understand how use the “cnlFilter”, what is this variable?

[Mikhail]

cnlFilter is an instance of scada.CnlFilter class.

[BrainBranchetti99]

Ok i understand the parameters required.

But for example if i need to read channel 1, 2, 3, 4 at the same time.
How i can pass this for 4 channels at the function? I call the function with a for or i have a metod for write in to the cn1filter my channels?

[Mikhail]

Try

var myFilter = new scada.CnlFilter();
myFilter.cnlNums = [1, 2, 3, 4];
myFilter.viewIDs = [1, 1, 1, 1]; // ID of the view containing the above channels
scada.clientAPI.getCurCnlDataExt(myFilter, function (success, cnlDataExtArr) {...

Hi Mikhil

Is there an equivalent function of getCurCnlDataExt() in version 6?

Kind regards
Matt

Hi Matt,

Web API became even better.
See this link.
Usage example.

I installed my scada on a new pc but now it doesn’t work anymore. I warn myself the following error: https://ibb.co/QvkgC0P

Let me know if you can see the image error.

Hello,

is there a way to read from js which user is logged into the scada? to allow the opening of the page or not

[Mikhail]

Hello,
See checkLoggedOn

[BrainBranchetti99]

Hello,
this function tells me if the operator logged in correctly.
I would like to know which operator did it for example between “user” or admin.
In order to enable some buttons to admin and not to user.
Finally, if it were possible to find an example that could be used.

Thank you

Hello,

I would like to know which operator did it for example between “user” or admin.

Currently, there is no such function. However, it can be developed.

[BrainBranchetti99]

Hi,
let me know how much it costs to develop the feature.
Also needed function to log out user from javascript.

David.
