Is there a method for F2152 with eHMI to detect the IP addresses of connected displays - preferably wirelessly connected iPads, but could be wired PxC webpanels, and then enable certain pages or display data based on the display IP address?
See this post for a related question: https://www.plcnext-community.net/en/discussions-2-offcanvas/ehmi-authentication-and-client-tracking.html The HMI_STATUS system variable gives you information about the connected clients. If you do not specify a ?StationID at the end of the URL, it defaults to the first index of the CLIENTS array. The information will be overwritten by each connected client. If you specify a unique station ID for each client, you can see the IP address of that client. With that, you still have to come up with a way of granting access to certain pages. The trouble being that if the PLC recognizes an IP address and makes certain buttons/functions available, it’s still available to all clients. One idea I tested was having a home page that simply allowed you access to different parts of the application. Based on IP address you were allowed to go one way or another. The problem of course, if both users hit the home page at the same time they would be allowed to go wherever.
Thanks for the pointer, Rob. I just discovered there is an ActivePage variable as well. Maybe the 2 can be used together to achieve the basic goal
