CM5-RHMI iOS App Resolution
I have a customer that wants to use multiple iPads on the Plant Floor as their primary HMI. Can I develop applications at 1920x1080 on a Headless RHMI and run them at full resolution using the iOS app?
I would expect that to work fine though I have not tried it. The CM5-RHMI is 1089p. The objects will be small on the iPad as opposed to a large monitor. I would recommend making screens specifically for the remote app and others for a monitor if you plan to connect one.
My iPhone 14 Pro is 2556x1179 (I think) and it displays the remote HMI screens just fine.
Keep in mind that the CM5 remote HMI's allow for a maximum of 15 remote users that can be active at one time, if all three user accounts are configured for the maximum setting of 5 each in the software.
However, they will all see the same screen. The iPad users can't be independently doing things in the HMI at the same time. So if user A changes screens, users B, C and D will also change screens.
If multiple users are connected with the ability to change screens or activate screen objects, it could cause confusion for all connected users. For safety reasons, we highly recommend that if panel controls moving equipment, that only one remote user is allowed to connect to the accounts that allow screen change or full control of the panel.
