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?

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?

[BrainBranchetti99]

I’m having trouble understanding how it works.
Would you have some practical examples?

Thank you.

The following function:
scada.clientAPI.getCurCnlData(CNL_NUM, function (success, cnlData){ …..

allows the reading of only one variable at a time. Is there a function that allows the reading of several variables at the same time? Thank you

Hi,

i use opc-ua.

[BrainBranchetti99]

Sorry I didn’t understand, my problem is to assign a channel to each location array without having to do it manually

[BrainBranchetti99]

Hello,

if it is not a problem for you could we discuss the following possibilities?
1. Send commands using the existing web form which could be opened from your custom form.
2. Use scheme views for displaying data.

Where can I find test examples to understand how to do it?
Thank you so much for the great support.

Davide.

> A custom page should not be accessed by disk path like C: \ SCADA… It should be accessed by a relative link like shown in the example (see readme.txt)

I did exactly as the test example says and it works fine. I always log in via the scada web app

[BrainBranchetti99]

Yes, I definitely need to be able to send the data too.
Let me know what to do in order to set up the communication.

It’s possibile to write data with the clientApi?

[BrainBranchetti99]

Good morning,
I realized that I was missing the ClientApiSvc.svc file in the custom folder

How do you write a value? Do the reverse?

[BrainBranchetti99]

You’re right it must be an iframe problem

I don’t understand what the console error means, is this what you meant?

I leave to you the error that i find:
