Hello, I am experiencing issues with a CPU314 and an analog input card that is supposed to read 0-10VDC input. Despite injecting voltage from a multimeter, the TIA Portal V17 does not display any readings. We have tested all channels but have been unable to receive any readings. We suspect that the AI cards may be faulty, there could be configuration errors, or wiring mistakes. To troubleshoot, we recreated the program in Simatic Manager V5.7 with the same wiring, card, and hardware configuration, and this time we were able to successfully obtain readings. Can anyone explain why the system works in Simatic Manager but not in TIA Portal?
What is the card number? Feel free to provide the numerical sequence for processing.

What is the process for obtaining readings in V5.7 and TIA?
L DA2RP 0.0 queried: How are you retrieving data in V5.7 and TIA? I watched the tags in TIA by monitoring them in the watch table and used the Variable table in V5.7.
When checking the watch table in TIA, make sure to utilize the P function to access input data directly via direct peripheral access, such as IW256:P.
It sounds like you've done some thorough troubleshooting already! One possibility for the discrepancy between TIA Portal and Simatic Manager could be how the hardware configuration is defined in TIA Portal. Sometimes, even small mismatches in the setup or even the settings for the analog input card can lead to no readings. Make sure you've double-checked the configuration settings to ensure they're exactly aligned with what's functioning in Simatic Manager. Additionally, TIA Portal tends to have more detailed configuration options, so reviewing those might help uncover an overlooked setting. It's also worth ensuring that the device descriptors and libraries are up-to-date in TIA Portal, as discrepancies there can lead to issues as well. Good luck!
It sounds like you're dealing with a tricky issue! Since you're getting readings in Simatic Manager but not in TIA Portal, it could be related to how the configurations are set up between the two environments. Sometimes, TIA Portal may have different requirements for addressing or configuration settings that aren't immediately obvious. Double-check the hardware configuration in TIA to ensure everything is defined correctly, and confirm that the analog input card is properly mapped. It might also be worth looking at the data types used or any scaling factors that could affect the readings. Lastly, ensure that the project is fully compiled and downloaded correctly to the CPU in TIA Portal. Good luck!
