Change Ewon parameters from a viewon page

Hi,

I got the question how to change a parameter of the Ewon from a viewON page, like for instance, the Logging interval of a Tag.

For this, I have used a Text object on which I have associated a "Text" animation to read the current parameter value

and a "send measure" action to change it :

In these animation and action, I have put some BASIC script that will be executed on the Ewon side.  The "viewon!" parameter is a static parameter that defines the returned value to the viewon page. ("Tag1" in the script is the name of the Tag that is modified)

Hi,

No problem.

1. Yes you can create two or more admins in eCatcher. However the eCatcher users are not the ones used in the viewon application. Indeed, the ones used are the Ewon users. In the Ewon, you can create two users having different viewon user rights.

2.Of course you can do that. Just read this : https://www.ewon.biz/technical-support/p...ion/modbus

what I want in the viewon, I create an additional page only educated to the administrator with password,  for example:
I have 4 pages of viewon, the first three for the operator and the 4 is for the administrator, an authentication is required to access it.
I hope i'm clear .
Thanks

Hi,

Yes, you can create view for the administrator and one for the user in viewon.
For this you have to
- Create a guest user in your Ewon
- Set the users rights in viewon (Project --> User management)
- Click the "Admin" views background --> Access Tab and select Administrators only.
- Click the "Guest" views background --> Access Tab and select "viewer, operators and admin"

The only thing is that if the logged guest user access the admin view, there won't be any popup to login again. He will simply see a white screen.
So what I suggest is to create a "Main/Index" view with a "guest view" button and a "admin view" button
