    SIMATIC S7-1500 S7-PLCSIM Advanced

    Document: S7-PLCSIM Advanced (12/2017, English)
    Type of topic: Fact

    MCR and EMCR

    There are Motion Control resources (MCR) and Extended Motion Control resources (EMCR) on each CPU that can be distributed to the technology objects.


    Note

    PLCSIM Advanced does not support the complete quantity structure of MCR und EMCR. The simulation of motion control is therefore restricted for the following CPUs:

    1 The ODK functionality of this CPU is not simulated.

    Exceeding the quantity structure

    STEP 7 checks whether the quantity structure for a configured CPU is complied with, and alerts you when it is exceeded. When you load a project into a CPU, another message appears.


    Note

    A project that uses more MCRs / EMCRs than PLCSIM Advanced supports can be downloaded to a virtual controller. However, there is no message indicating that the quantity structure has been exceeded.

    Only when the user program accesses the technology objects do you recognize by the error message at the block and the value 0 of the object that motion control objects cannot be used due to an overrun of the quantity structure.
