In the automation world, a simulated test environment, including the controller and process, reduces the commissioning times and thus reduces costs. Through early detection of programming errors and early optimization of program sections, the programs are already error-free and optimized when used on the plant. If there are program changes, it is possible to test the program before it is loaded into the plant controller. PLCSIM is a fundamental part of STEP 7 Professional (TIA Portal).
