Hello dchartier, if only the user program has been downloaded to CPU, is there any kind of blocks that will indicate that a download has been performed? if yes, does block/s contains dates when the download is performed? I have a project 5yrs ago (2018), I came back and check the history per maintenance. in October 2019 a vendor update, change and download new user program to PLC which I see now in the blocks online and with the offline program and all blocks are stored in EEPROM except for 1 FC that is stored in RAM and this FC contains logic 5 years ago as indicated in the last modified date of the block. Now I was task to investigate how this block came to online user program when the at first place the vendor in 2019 clearly said that he updated all the blocks both online and offline. Is there a way to trace or to know when the last download for this FC was done? Is there any blocks that will indicate time, dates for this change Is there any files that will indicate that a recent download to PLC was performed? I only see SBDs with their type numbers (i.e. 0-2000) indicating dates of 31/01/2022 Thanks, ------------------------------------------------------------------------------------------ |

Closed cause question posted twice. The second thread with the subject Is it possible to check in the Simatic Manager when the last download was made? is published within the conference STEP 7 / STEP 7 Lite. Jen_Moderator |
