Hello,

I have an old project i did 2 years before, now i need to make a few changes but somehow i cant seem to connect to my hmi. I could access my plc easily but i cant access my hmi.

So i open my pc, and then i try to download, and it cant find the device at all. But if i try to go online i can see it as accessible device. And when i try to connect it assigns an additional ip address(192.168.0.241). And after all that, it gives me an error saying "Connection failed; The selected online target could not be reached"(screenshot added for that).

When i try to flash the light of the hmi, it says "Flashing failed. The selected online target does not support flashing or is not reachable"

What stumbles me is that when i connect my hmi back to my plc it works without a problem, i can connect to plc and on connections it says that adress for the hmi is "192.168.0.12", I tried making my pc's ip static "192.168.0.94". Didnt work at all, now i cant even connect to the PLC. So i returned back to my old setup, at least i cant connect to my plc

Please Help

Hello,

thanks for the reply, i apologize, Now i added a screenshot of the device seen without the error.

Hello Emhyr

why do you want to go "online" with an HMI -> It will not give you any further advantage (its not the same as a PLC; do not go online to an HMI before you want to load it).

You should try to transfer the HMI project to the Panel with this steps:
