LED BF display for CANopen
In addition to the signal states "on" and "off" there are three different flashing frequencies:

GREEN - on Bus state "Operational"
GREEN - fast Bus state "Pre-Operational"
GREEN - single flash Bus state "Stopped"
RED - on No bus
RED - single flash Alarm - limit reached
RED - double flash Error event in control (Error Control Event)
YELLOW - variable

9.2 System runtime
By evaluating the system runtime of the inverter, you can decide when you should replace
components subject to wear in time before they fail - such as fans, motors and gear units.
Principle of operation
The system runtime is started as soon as the Control Unit power supply is switched-on.
The system runtime stops when the Control Unit is switched off.
The system runtime comprises r2114[0] (milliseconds) and r2114[1] (days):
System runtime = r2114[1] × days + r2114[0] × milliseconds
