Simulation Aided EngineeringFrom Single Unlinked Tools to Test & Simulation Knowledge Management
TIA-Portal PCS-7
Simulation Unit PLCsim
Each of these tools has certain test and/or simulation capabilities, butThe capabilites are not linked to each otherFunctionality is fixed and cannot (easily) be extended to customer‘s requirementsNo or only limited scalabilityNo common systematics and methodicsCode is changed in controller for test and simulation purposesNo test knowledge management possible
SIMIT
One tool for all simulation and test tasksGraphical project creation (understanding simulation tasks !!!)Makros, Templates & Components = Put simulation and testknowhow into reusable units = Build up test & simulation„Knowledge Management“ Scripting & Snapshots = Automate test & simulation tasksEasy exchange of components with newer version (search & replace)No changes or extension of controller program codeFully scalable simulation (from signal over sensor/actuator to process)

Test & Simulation Knowledge BaseWhat has to be tested?
IO-Simulation (setting signals and values)
Basic actions of actuators and sensors
Basic behavior (startup, shutdown, basic operation)
Advanced behavior (product change, load change)
Basic malfunctions
Borderline situations, endangerment

• Knowledge is in the head of certain people. It is not usable for others.
• Even experienced engineers have to remember. And they do also forget!
• What happens to unexperience engineers???
Non comformance costs, unsatisfied customers, bad references

• Test case by test case is implemented in the simulation tool• Growing knowledge based is structured by macros,
templates, reference projects and components• Knowledge base is usable by any person
Early detection of failures and short correction loops
Now my job got easier!
