Why can't I see some parameter values in simulink?

I am an engineer in the field of new energy power generation.I found that I can't see some parameter values When I'm ready to find inspiration from the examples of matlab model. As shown in the figure below ,How much is "sps.CmdModulatingSignals" exactly? Where can I check this parameter values? (Detailed Model of a 100KW Grid-Connected PV Array,matlab 2013b)

It has been my experience with SimPowerSystems (which I assume sps stands for) that they mask several of the implementation details. There are probably doing this for a couple reasons, (1) so they can make the code more efficient/clean/flexible/whatever, (2) so they can try to stop you from stealing their models and they can continue to charge $$ for them.

When debugging, I have had some luck with breaking library links and running scope outputs out of the models. Or you can sift through the documentation, sometimes it is very explicit about how things are implemented.

Thank for the answer and attention! It seems that i only to build a model by myself. Why don't "MathWorks" give a basic sketch to interpret their models! sigh!!!

Did you contact MathWorks without receiving a good answer?

Hi Because I'm using a trial version,they do not provide technical support.So I came here for help. sigh!!!!

Users with a trial version do get technical support. If you experienced differently, please let me know the details. You find my email address in my profile.
