Doubts with Vismach

Hello everyone, I have been reading a little about Vismach and without a doubt it has a lot of potential, but as a good student I have some doubts, I have seen how to declare hal pins in the python file that describes the model of the machine and of course being able to read them from el hal, so far so good.
I would like to provide the model with limit switches and home switches and be able to use that behavior in the hal, I imagine I have to make some loop where I poll the current position of the axes at a fixed time interval using a timer or something similar, these are just ideas in case someone can shed some light on the subject, thanks in advance.

Hello Aciera, I have followed your approach and to my surprise linuxcnc brings a simulation module for sim home switches, that is, everything has been as easy as loadrt sim_home_switch, configuring parameters and connecting signals, thanks anyway, greetings
