Need help! Advice for post processor for SINUMERIK 840D sl

Hi, is here someone who can explain me, the meaning of the bits in Sinumerik drilling cycles (Sinumerik 840D sl) in the program file?
I need to ad cycle830 in a post processor for Solid CAM, but can't find any information, which bit what is it.

Also... just wondering, is it possible to run a simulation in the control, whit machine limits (like in HEIDENHAIN, If some move on some axis is too big, to show error message).
If it is possible, how exactly can make this?

Thank you very much for your attention, and will be even more thankful if someone really help me! :-)
