9.4.2 Diagnostic Header
The header information shows the length of the diagnostic data (including the header byte) in
hex format. Octets 7 to 16 = user diagnostic data.
9.4.3 Alarms
Alarms are triggered when a serious error occurs in the encoder system. The message is de-
leted when the master has read the complete diagnostic data. The error display, too, will then
no longer be present.
Each correct detail within the supported alarms/additional alarms also triggers the alarm-specific
Commissioning Diagnostics Alarm Bit.
