System-Used Signals¶
The following chapter describes a set of predefined signal keys for standardized functions on the DataPortal. It is recommended to use these unified keys.
Note
If possible and available on the machine, these metrics should be transferred to the DataPlatform and parsed by the PDC.
Note
Some of these functions must be enabled for your account as special features.
Counter Guard Signals¶
Counter Guard detects counter violation events in machine counters. A counter violation is a period in the time series in which the signal behaved suspicious. This is done by checking the monotonicity of the time series.
For more information on the usage, see DataScience Manual → "Counter Guard".
Note
All signals that represent a monotonous counter (e.g. operating hours, total fuel consumption) should be defined as category xsi:type="Counter" including naming the counting direction, in the PDC Value Definition.
Fuel Guard Events¶
The Fuel Guard feature detects four different types of fuel events. They are Fuel Refill (Refuel), DEF/AdBlue Refill, Fuel Loss, and DEF Loss events. For more information on the usage, see DataScience Manual → "Fuel Guard".
Mobile App¶
To use the complete Machine Companion App function set, the following keys should be used in the PDC for the signals shown in the table below.
You can also use a fully customized signal list based on OEM configuration, i.e. custom signals instead Proemion standard signals.
You can also use aliased signals over Proemion standard signals, if defined. For more information, read the Machine Companion App Manual or contact your Sales representative at Proemion.

Machine Efficiency¶
The machine efficiency can be calculated of any work signal that is defined as Counter, e.g. machine operating hours, and idle signal, e.g. fuel consumption, over time ("total"). For more information on defining Counter type signals see Counter Guard Signals above.
