hello SolutionFinder; I am sorry but I must diagree with the statement above. Work memroy is not expandable, load memory can be increased using RAM or FEPROM modules. See the following text: SIMATIC S7-400 S7-400 Automation System, CPU Specifications Flexible memory space ● Work memory: The capacity of the work memory is determined by selecting the appropriate CPU from the graded range of CPUs.(Note: this translates to "the size of the work memory is fixed per CPU" D.C.). ● Load memory: The integrated load memory is sufficient for small and medium-sized programs. The load memory can be increased for larger programs by inserting the RAM memory card. Flash memory cards are also available to ensure that programs are retained in the event of a power failure even without a backup battery. Flash memory cards (8 MB or more) are also suitable for sending and carrying out operating system updates. Hope this helps, Daniel Chartier |

Dear dchartier, Thanks a lot for your reply. Actually I was little bit confused with load memory & work memory. You had cleared my concept. Thanks a lot. |

Hello vipz have a look at the threadIncreasing PIP & PIQ vs. peripheral addressing which should answer all you questions on this matter (I hope). |
