Has anyone made a working image back up on a Comau c5g? What software would I need? Replacing a bad APC with a new one only requires the original uncorrupted Flash card. I tried to copy a good running flash card to a card from another APC that is good using my PC. I only deleted the contents on the card getting the copy. I didn't format it. When I swapped the copy with the original, It didn't have any programs, encoder values or robot ID name on the home page and more. It seems not everything was copied over to the extra card.

Yes, I've seen it done in USA, Turkey and Italy, but never within the community of robot programmers, rather by maintenance departments at the plants.

There are a ton of programs that can do an image, Win32DiskImager is one of my favorite.

The issue with CF's has many roots:

- Comau C5G's have used, since 2010 three different models of CF. Different model may mean different underlying control technology, there are PATA, SATA, CFast technologies used. So if you buy a new CF to write an image, better you pick the right technology. Sorry I wouldn't know which is which (I believe though the earliest CF were Western Digital PATA), but it's an information that can be dug out. Technology used should be readable on the CF you pull out of APC820 or APC830.

- I was told your CF reader might be the issue. Somebody "in the know" had different results with different readers. This may relate to the previous point.

- CF images on C5G are not "trimmed", apparently, they use to the last byte available. So you write to different CF with a different byte count and you have issues. I don't know what to recommend here. Linux is your friend and you can do some trimming, I don't believe 2 KB on a partition would end up making a big difference.

Comau knows you really need to know what you are doing to clone a CF, so they are normally perturbed if they find a Customer with a CF that is not original.

An email to service.robotics@comau.com will also help.

I dug out some information on the three different CF's used on Comau C5G's. This information may change in the future as CF's are a commodity and a more suitable CF supplier may be found at any time.
