Hi, TheS7-1500/S7-1200 store the comments of the program, S7-300 not. This makes a significant difference in the load memory usage. This "read back" feature permits also that the stetical disposition of the instructions in the block could also be "uploaded". That means that the block is not more that a simple code, but the whole source archive should be stored in the CPU. This takes also more memory. Take a look at a program comparation for LAD at /tf/WW/en/Posts/88783#top Stays the "feature" that consecutives compilations of the same program generates differentes memory consuptions (little differences) (/tf/WW/en/Posts/89151#top). This makes also difficult to get a precise formula to calculate the memory consuption. |

May be this is the reason why S7-1500 Load Memory (Simatic Memory Card) begins with 4 MB and a max of 2 GB (as of now) unlike S7-300 begins with 64KB and a max of 8 MB. |

New question published by Willybong is split to a separate thread with the subject S7-1500: Not enough memory to load. Best regards |
