Hello,
Kindly have a look at the following topics: 1-How can I get an overview of the S7-400 memory concept? 2-How can you write the program to the FLASH Memory Card when using a SIMATIC S7-400 CPU? Programs stored in RAM are lost when you reset the CPU memory (MRES) Programs saved on memory cards are not erased by a CPU memory reset and are retained even without battery backup. |

Thanks Panov 69 and Online Tech for the answer. I just got the following information: CPU: 6ES7416-3ER05-0AB0 and Memory Card: 6es7 952-1am00-0aa0 which is a RAM. Now to download the code, can I just download to PLC? Do I need to delete anything from the memory card? is the older version of the code going to remain on the memory card? I would appreciate your help. I am all new to this world and this is my first project with S7 400. Thanks. |

Hello, 1-Upload the program from the CPU and save it in a safe place. 2-Do the modifications in a copy of this program. 3-Download the new codes"the modifications" which are override the old codes in the CPU only. 4-The other codes remain without any change. 5-No need to delete any thing in the memory card. Warning:If you remove the RAM Memory Card from the CPU, you lose the data and files stored there. With the RAM Memory Card, the battery or power supply of the CPU is necessary to ensure that the data and program are not lost on the memory card. --------------------------------------------------------------------------------------------------- 7-How can I get an overview of the S7-400 memory concept? 8-How can you write the program to the FLASH Memory Card when using a SIMATIC S7-400 CPU? |
