Hello SIOS Forum Community We would like to give you a hint on how the remanent data is preserved during a firmware update for the SIMATIC controllers S7-1200/S7-1500 are preserved. In principle, the remanent data is retained during a firmware update. This is described in the system manual of the SIMATIC S7-1500 in chapter 13.5: The same applies to the S7-1200, but there is currently a different project behaviour in the current firmware V 4.5. When updating to this version, actual values are initialised with the start values. Details can be found in the FAQ: "Note on project behaviour during FW update V4.5". Best regards, SIMATIC International Technical Support Hub |

Hello SIOS Forum Community The different project behaviour described for the remanent data in firmware version 4.5 of the S7-1200 has now been corrected in version 4.5.1. This means that the remanence memory is retained after a firmware upgrade from V4.x to V4.5.1. For the individual S7-1200 controllers, the download is available in the SIOS Best regards, SIMATIC International Technical Support Hub |
