A.2  System events 
System events on the HMI device provide information about internal states of the HMI device 
and PLC. 
 
 
Note 
System events are only indicated if an alarm window was configured. System events are 
output in the language currently set on your HMI device. 
 
System event parameters   
System events may contain encrypted parameters which are relevant to troubleshooting 
because they provide a reference to the source code of the runtime software. These 
parameters are output after the text "Error code:" 
Description of the system events   
A listing of all system alarms for your HMI device is provided in the Online Help of your 
configuration software.
