3.4.8.4 Special notes and limitations
• Max.loglesize(duetoFAT32formatting):4GB
• Max.numberofloglesinfolderHMI_FILES:1024
• With setting “Start/stop with DC on/off”, the logging will also stop on alarms or events with action “Alarm”,
because they switch off the DC output
• With setting “Manual start/stop” the device will continue to log even on occurring alarms, so this mode can be
used to determine the period of temporary alarms like OT or PF
