Hi everyone, I’m facing a recurring issue with the WAGO CC100 Edge Controller related to SD card detection after rebooting the system. Setup & steps taken: Controller: WAGO CC100 SD card formatted using the Web-Based Management (WBM) interface: WBM > Mass Storage > Create New Filesystem on Memo…

We received our new batch of SD cards today (both 32 GB and 16 GB) and immediately ran some additional setup tests. Interestingly, the issues we were experiencing no longer occur with the new cards. [image] Dr.Fix: I’ll still give it a shot and see if I can get the currently problematic 32 GB c…

Hello Can you confirm the SD card is a high quality model (SanDisk for example). Some lower quality cards have been found to have quality issues. Curious, have you tried smaller cards, 16GB, 8GB etc?

Hi @WagoKurt , thanks for the reply. Yes, I can confirm that. We use SanDisk cards purchased from a trusted retail shop. We still have some 16 GB cards (also SanDisk) lying around, and I’ll run another test with those tomorrow to see if things work better with them. I’d be surprised if that made a d…

Hello, I think there is a problem when something is trying to use the SD card before it is mounted and so it create the folder SD instead of waiting for the link to be there. For myself I’ve made a symlink in the codesys folder: ln -s /media/sd/ /home/codesys/PlcLogic/sd if the SD card is not the…

@WagoKurt , today we tested another batch of SD cards. Also SanDisk, but this particular batch has been lying around here for a while. Interestingly, the setup worked reliably again with these cards – both 16 GB and 32 GB versions :partying_face:. The CC100 correctly detects the partitions, even afte…

Hello, if you can it would be interesting to see if the cad have some bad memory block which make its controller take longer time to enable it and put it online.

It would be interesting to see if the SD cards you have support S.M.A.R.T feature [image] How To get memory card life time expectancy Hardware and Linux If you wish to get the life time expectancy of a WAGO memory card, here is a solution. 8Gb WAGO memory card support S.M…

Indeed, but can we do this in the PLC (Like PFC200 or PFC300 ?)

I analyzed the SD cards using my Ubuntu machine and the “Disks” tool. Everything looks fine — no irregularities, errors, or damaged blocks were found. I also ran the two tools h2testw and Validrive on my Windows machine, again without any issues or warnings. Do you know / recommend other specific t…

Unfortunately I wasn’t able to get the S.M.A.R.T. tool to run. On the CC100 I’m getting errors indicating that FUSE is missing. Is it even possible to use the sbdm-cli binary directly on the CC100, or would I need to run it in a Docker container that includes the necessary libraries? I couldn’t get…

This is weird, it does work on my CC100. Which CC100 is it ? Which Firmware version are you running ? I used the latest, FW28. Note that Swissbit also provide a S.M.A.R.T tool for Windows : Swissbit Device Manager - Swissbit The Swissbit management tool to analyze the usage of Swiss…
