Hello everyone,
I am developing a new machine using a WAGO PFC300 and two WP400 panels (two different clients and two different instances of WebVisu).
My service manager requires the possibility to monitor the HMI user activity step by step: when the user presses a button, changes a page, etc. – basically a mirror of the screen.
At the moment, we have a VNC server installed on the HMI, and in read‑only mode the service technician can follow the user activity during maintenance interventions (OpenVPN connection).
I don’t know how to develop this feature with WAGO. Do you have any ideas?
Is it possible to install a VNC server on the WP400?
Regards,
Hi Lorenzo,
we had the same problem with the WP400 panels, unfortunately wago service told us that the panels doesn’t have some requirements for the vnc to work directly on it (maybe you could try something with docker).
For the webvisu if you want all syncronized you have to check the “use CurrentVisu” variable the visualization manager, for the dialog the best approach I found was to use the function blocks FbOpenDialog FbCloseDialog (at the end I used also the FbChangeVisu)
Thanks.
I will try to use the VisuUtils library, but it’s a complex solution to solve this issue… VNC is an easier way, but…
Do you know if it’s possible to have a client in read-only mode?
You can set up user management and then require a login to access the interactive aspects of your visualizations.
