Initial condition from external source for discrete integration diuring runtime

I have a discrite integration with simulink and externaly added the condition:

when changing the value of external source (in my case mec_init_pos) - does it have influence on simulation integration or just for strating simulation and very first initialization of the integration?

The value of "mec_init_pos" could be constant or dynamic, but in this case, only its value at the begining of the simulation (e.g. t=0) would be taken to set the initial value of the integrator.

When you enable "external reset", then the dynamic value could be taken depending on the external reset signal.
