    This work contributes towards straightforward simulation model transformation from early engineering phases into automation testing of process plants. The work was conducted in the Engineering Rulez research project, under the task T2.2.2 “Toolset for automatic transformation of analyses simulation model into testing model”. The focus was in easy switching be-tween different automation solutions, such as safety logics in the Apros model and an emulated actual system, and comparison of the results from these systems. Besides Apros, the environment for automation testing includes the new version of the Testing Station software that has been developed in other tasks and sub-projects of the Engineering Rulez project.
    New modules were designed to support the switching between alternative automation circuits in the Apros simulation software, taking into account the result comparison feature. The relevant options for implementation are discussed in this report. In addition, sample implementation of Analog and Binary System Switches using the User Component approach were experimented and the main findings are reported and discussed.
    The value comparison part of the original project plan did not proceed to implementations. That was decided to be left done after the current active development phase of the Testing Station 3 software. An important detail question discussed in this report is to find the best way to sup-port multiple violations for the Violation Monitors feature so that the comparison continues through the entire test sequence.
