Reading value of pin in g code

Yes, you're right. I made a test, just left one if and programme missed this loop. It goes from 8th step to 30th... altough that P11=%Q11=s1 has a high state. What's wrong ?

Can you attach the G-code file, so far we have only seen it as a screen-shot.

Can you have a halmeter look at the actual value of motion.digital-in-11 (and 12, and 13) rather than assuming that the HAL net is working?

Did you increase the number of digital inputs in the loadrt motmod line?

Hal meter shows that Q11 etc. is TRUE.
I changed L0 to L3 for some tests.

Can you insert a (debug, line-no #5399) before each "if" to see what the actual value being used is?

I saw that when the 4th line is running then one of chosen pins P11,12,13 works correct, but only once and after this i can't do anything.

That's how my code looks like at this moment. Loop works ONLY when the last step is running. It means that when line 23, 43, 62 is executed i need to set high state on P11,12 or 13 and then it works...
