Multiple Hmi Handling with One VC4

Ask Questions
1

Hello All,

I have an Electrical Shaft Printing Machine with 8 HMI stations, where each HMI handles individual station functions for its respective station.

Currently, I have created 8 separate visualization screens (Visu) in the project—one for each HMI.

I would like to know if it is possible to create a single common visualization that can be used across all HMIs.

Please note, all station control variables are of the same structured type.

Thank you.

You can define a VNC object in the Ethernet configuration of the CPU as a VNC server and then set several HMIs to the IP address of the CPU with the same port (default is 5900), e.g. 10.10.125.10:5900
This makes the CPU the VNC server and several HMIs can access this server

You can also set several VNC objects in the Ethernet configuration and change the port.
e.g.:
HMI-1 = 10.10.125.10:5900 = VNC object 1
HMI-2 = 10.10.125.10:5901 = VNC object 2
HMI-3 = 10.10.125.10:5902 = VNC object 3

Thanks for reply,

But I have a doubt about how to do tagging in VC4 for this?
Currently I do each individual station with individual HMI’s.
What I have need to change in program for mapping of HMI’s tagging.

Thanks.

You can have a single VC4 visu and deploy it multiple times but then all of them would point to the same variable which is most likely not what you want. For this type of visu you should use mappView. It would work perfect for that scenario.
