Good afternoon,
I'm having some HMI communication issues with FactoryTalk View ME. I'm trying to make an update to an existing program that has already been running, but when I download the updated runtime file there is no communication at the HMI, everything is showing ???'s.
I save the runtime as a new filename and load the new application. I press No to the "Replace communications with the application communication setting" question so the communication setup should not be changing.
Unfortunately I am not able to upload the most recent file from the HMI because the runtime was created and set to "Never Allow Conversion". So I'm using the most recent development file I could find of the program with the same name as the current runtime file.
I've also gone into RSLinx Enterprise and made sure the runtime (target) communication setup that's selected is exactly the same as what I see under "Application Settings->Device Shortcuts"
If I'm not selecting to change the communication setup, and using what should be the most recent file, I can't figure out why I am not getting any communication after making the update?
Is there some other setting in FactoryTalk that could have been changed somehow that is keeping the communication from working?
