We use CtrlX with WebIQ to make an HMI to control a machine (see photos below for the config), we use datas from the datalayer, and we read it from WebIQ with OPC-UA. we use a display and Chrome as Browser to look at the HMI and use it.
The link between the datalayer and webIQ is done and it works well most of the time. The thing is that sometime, when we starts the CtrlX and the screen up, the connection does not work, we proved it by using a boolean with a fixed value of TRUE in the datalayer, and when this boolean is read (through OPC-UA) at "true" value in WebIQ, the red sentence at the top of the screen disappear.
When the problem comes up, I open WebIQ designer to look at the connection state, and It looks to be ok, then I open the HMI with the "browser preview" and it works there. Then I go back to the "real" HMI in the same browser, and it does not work... (see photos attached)
The only way to solve it until now is to restart the system until it works...
Did you already get this issue ? do you have solution ?
thank's in advance,
