Hello Ahmed; If your program was damaged when power was lost you probably have the program saved in RAM, while the RAM memory supporting battery power is low. To make sure what model we are discussing, it would be useful that you give us the part number of the CPU and of the memory card, if there is any inserted in the CPU. In the meantime have a look at this document, discussing the memory concept of S7-300 CPUs. https://support.industry.siemens.com/cs/us/en/view/7302326 Hope this helps, |

Hi Daniel, Eventually I could hardly reach the site and sorry for being late. CPU PN / Firmware: 6ES7 318-3FL01-0AB0 / V3. 2 For the memory card I couldn't take it out to get the part number in order not to stop operation but I am attaching some photos that may be useful to you. If they are not useful and you still need the memory card PN just tell me to do it in next operation stop. Or if you have a way to get memory card part number while PLC is running just tell me. Thanks for your cooperation. Ahmed AttachmentPLC.docx (244 Downloads) |
