I think you shoud check the set PG/PC interfae from the control panel or from PLCSIM.

FAQ During communication, there might be time restrictions because S7-PLCSIM does not support real time.

Changing the operating system property "desktop heap memory" Even if you have sufficient main memory and export memory in your PC, you might get the error message "Not enough main memory" or the program might crash when running a large number of Windows programs. One remedy is described in Table 02. Best regards Hamid Hosseini
