Iq-select-box

[HugoCtrlX1]

Hello

Is possible you can recomend an example to read drive parameters (S and P) using iq-select-box or another way to read a list parameter from drive to show in web panel. 

Thank you

Can you please elaborate on what "drive parameters" are?

[HmiGuide]

When I understand your question correct, it includes 2 different tasks:

1. Read drive parameters
2. Display a list in WebIQ

1. Read drive parameters
I'm not really familiar with the drives, especially there are different fieldbuses for the drives, which means that retrieving the  drive data is dependent on the fieldbus, but my expectation is there are 2 ways:
- Read the drive parameters in the PLC program and provide that information to WebIQ
- Check if the drive parameters are available on the data layer, than you can use the ctrlX REST API to read the information from there.

2. Display a list in WebIQ
- There is an example somewhere on the SmartHMI webPage.

Regarding 2: the scripting demo includes an example: https://demo.smart-hmi.com/scripting-demo/

Hello

thank you for information, I am following this example, is possible you can suggest me, how to progam scrip to read and write variables from OPC-UA

[webiq-sk]

As I wrote above this is included in the scripting demo. Please familiarize yourself with it. You can download it directly from inside WebIQ Designer and look at the very well documented source code in Code Manager.

You have to load the project into WebIQ Designer, then open Code Manager and have a look at the scripts. These scripts are very well documented:
https://demo.smart-hmi.com/scripting-demo/js/custom-libs/local-scripts/demo-item-subscribe.js
https://demo.smart-hmi.com/scripting-demo/js/custom-libs/ui-actions/demo-item-readdirect.js
https://demo.smart-hmi.com/scripting-demo/js/custom-libs/ui-actions/demo-item-writedirect.js

If you do not know JavaScript there is a lot of information available online to cover the basics.
