3.5.13 Oscilloscope function
The implemented oscilloscope function is an important aid to help the commissioning
party optimise the controller settings without using a separate measuring device. The
function allows important signal sequences to be recorded over time. It consists of three
blocks:
• The initialisation section which runs at low priority and performs pre-calculations for
the actual measurement process.
• The measuring section runs at a high priority in the rule interrupt and records the
measuring channels. If the trigger condition occurs, the measurement process is
cancelled after a defined number of scan steps.
