How to stop dead code elimination when using Simulink to PLC coder?

For instance I have this Simulink model. When I generate PLC code, it leaves out the part of the model for which the conditions in the switches aren't true. How do I get it to generate code for the entire model regardless the choices of the switches?

Please provide the following information so that the community members can better understand the issue:

1. The Target IDE for which you are trying to generate the PLC Code.
2. Please confirm if the Simulink model has any unit delay blocks.
