From the developer:
SIMATIC S7-PLCSIM simulates a controller for functional testing of user blocks and programs for S7-300 and S7-400 on the programming device/PC. Online access and test functions of the programming tools can be carried out in exactly the same manner as with a real controller. This allows the entire program test to be carried out on-site in the development office.
