Not too familiar with this program language yet, but I've encountered things like this before using Logic for PLCs, not having privilage or access to certain points, software, hardware, etc. Could you say, IF interruption happens, and (network, earpiece AND microphone, or etc) are used, then DISPLAY start time of interruption, end time of interruption, (difference between the two) and duration of interruption. Just because you can't have specific access to those certain features, what makes those features present in the programming can you access?
