Hello Mr. Sohrabi; This document explains the memory concept of a S7-400, and indicates that adding a memory card, either RAM or EEPROM will not affect the available working code size of your CPU. A new memory card only affects your load memory. https://support.industry.siemens.com/cs/ca/en/view/7302549 A S7-400 allows you to partially reorganize the main (work) memory, but there are considerations in doing so. Look at the screenshot below. Basically, if your work memory (open the CPU Properties/ Memory, in HWConfig, while online) is the bottleneck, your only option is to move to a CPU with larger work memory. Show us a screenshot of the memory usage of your CPU, and we could help you evaluate your options. Hope this helps, Daniel Chartier |

Definitely, if I do this test I will share my report. Thank you for your consideration. |

Presuming you are using classic Step 7 V5.x, simply right click on the Block folder, select "Object Properties" go to the "Blocks" tab and it'll tell you your Users program Work and Load memory requirements. |
