If I try to revert back to the original file, won't I have trouble running it on the updated firmware? It's lack of experience with these questions that makes me hesitate. My question: What if I upload the file, make the changes, find that the changes require to update the HMI's firmware, and then there's a glitch after updating the firmware that keeps the HMI from operating correctly with the PLC (and the older file on the PLC). So I will save the program before doing anything, when that time comes. I do have Prosave on my laptop, as well as the plant's laptop. This is also giving me time to fill some of the gaps in my knowledge of Siemens systems. The changes I'm hoping to make are not urgent, so I'm being overly careful not to make a mistake that would create downtime. I'm still waiting for a lull in that side of the plant so I can log off of the runtime software and check the panel's "Documents" folder for the file I was told was stored in the HMI's memory. I schedule this customer for Mondays and Thursdays, unless someone else has an urgent need (and my Siemens customer doesn't). Am I correct in thinking I can edit the file without it being integrated into Step 7? (My version is 5.5) I'm also wondering about backing up the HMI, so if I mess things up, I could restore the un-edited version.
If I need the same version, do you know how I would get a working copy of that version? As you see, it's also integrated into a Step 7 project. What do you guys know about compatibility for uploading, then downloading back to the HMI. I tried calling tech support to see if I'm able to get a 14-day version of that legacy WinCC, but they would have to charge me money to even ask that question. My customer has version 2008, SP5 on a Siemens Field Service PG, running Windows 7. My laptop has WinCC Flexible Advanced 2007, Build v1.2.0.0_1.55.0.1., which is on Windows XP. The part that I'm questioning is when he said I would need the WinCC version it was programmed with.Īs you see on the pic, it was WinCC Flexible 2005, SP1.
He said the program file is saved on the HMI, and the box is checked for being able to transfer the HMI file back to the laptop. I want to make some edits to the HMI to make it easier to use, and easier to train new employees. I was able to email a programmer who worked for that company when they installed the machine at my customer's plant. My customer has a machine that was made by a company no longer in business. I need some help with compatibility details.
