Long story short.....
Customer : We want you to replace this hmi with a direct replacement. We don't have the original hmi program.
Me: OK, I get a backup image on a USB thumbstick and load it to a brand new direct replacement hmi in my home office.
Me: Go back to location, customer states, oh by the way we nuked the HMI trying to change the ip address.
I install the new hmi and power up the replacement, update the ip address. Start the runtime to see all the place holders are starred out for all values. (no comms to plc)
What are my options gentlemen? Is there an easy way to link this new hmi to the existing unchanged plc in Tia portal? Or do I need to start from scratch?
Interesting note: the original plc program network view does not show any comms link to any devices. How did this ever work before?
