Hi Telo, this are two different storys. If you rollback/change the firmware in the project you can transfer this to the CPU even if the CPU itself runs with a newer firmware. To downgrade the firmware of the cpu itself, you need to install the firmware like you did in the second step. The dependencies can be found here: Firmware update for CPU 1214C, DC/DC/DC, 14DI/10DO/2AI-> "NOTICE: S7-1200 CPUs with Functional Stand 05 (FS: 05) or later cannot be downgraded to firmware versions prior to V4.2.0." In your screenshot of online diagnostics you can see that the S7-1200 has hardware version (FS) "14" . Long story short. You can not roll back the firmware of your S7-1200 to V4.1.x. regards sancruz |
