The key code can bee seen very well in the integrated oscilloscope:
8 Switch on the machine.
8 Press the EMERGENCY STOP button.
8 Call the integrated oscilloscope. --> See ”Integrated oscilloscope” on page 10 – 95.
8 Make the following selection:
8 Start recording.
8 Press several keys.
8 Stop recording and adjust the signals.
8 Restart recording.
8 Press the key to be examined and check, if the integrated oscilloscope produces an amplitude
or if a reaction takes place that corresponds to this key.
The key code is of secondary importance. Important is, whether or not the control detects the
keystroke.
