How to use Fast Measurement inputs?

I use KRC4 and Heidenhain Probe TS 460 with SE 660 for interrupt activation. The sensor works correct and gives trigger signal. The trigger signals connected to 2 and 3 (inverted trigger signal) outputs of X33 socket. How I can see it at robot side? How to declare it (INTERRUPT DECL 21 WHEN = TRUE DO STOP() )?

Can I see does it work without running the program? Similar to Display > Analog I/O

Ohh. I tried to see the $meas_puls[1] (or any [1-4]) in Display->Variable->Single, but it didn't work. There is no error. I just see "" (Quotation Mark). I checked all connections and sensor really gives trigger signal to first pin of X33 socket or second pin of X23 socket. What can be the problem?

I corrected it manually, but...

it was only single line of code:
</MeasureChannels>

I changed all to:

<MeasureChannels>
<MeasureChannel ID="1"/>
<MeasureChannel ID="2"/>
<MeasureChannel ID="3"/>
<MeasureChannel ID="4"/>
<MeasureChannel ID="5"/>
<MeasureChannel ID="6"/>
<MeasureChannel ID="7"/>
<MeasureChannel ID="8"/>
</MeasureChannels>

But again it didn't work

I forgot to restart the KRC. Cold reboot did all trick. Thank you
