Notice
In the event of the failure of a machine control panel connected via MPI, the
following alarm is triggered by the PLC basic program:
S Alarm ”40026x machine control panel (x+1) failure”; with x = 0, 1
When connecting the machine control panel via PROFIBUS, the user (machine
manufacturer) is responsible for triggering a corresponding alarm.

A key and the LED positioned above it form a logical unit. The key and the LED
have the same number.
S Key number xy corresponds to Sxy
S LED number xy corresponds to LEDxy
Fig. 8-20 shows the arrangement of keys and LEDs on the machine control
panel. For the sake of clarity, the LED designations are not shown in full.
