Modify the simulation files

To update a simulation on a production system, you must make a local copy of the .simx file that's in the AVEVA Process Simulation repository for the running production system. Make changes to the .simx file in your local AVEVA Process Simulation repository, and then update the sequence folder with the updated .simx file.

Modify a simulation file

1. Ensure any related sequences are not running in the production AVEVA Real-Time System (RTS) system.

2. Open your local AVEVA Process Simulation, which has its own simulation repository.

3. Import the simulation from the production system into you AVEVA Process Simulation instance.

   You do this by accessing the Sims folder of the RTS service account.

4. Edit the simulation in your local AVEVA Process Simulation system.

5. Export the simulation and copy it into the sequences folder (overwriting the previous one).

6. Restart the sequence-related operation (backfill run or schedule).

   The cycle script automatically imports the modified simulation when it runs.

   Cycle scripts should unload any simulations by calling sm.CloseOpenSimulations(). on shutdown of the sequence
