Output Description¶
Function Block PUMP_ENERGY_CALC
DONE
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
Output indicates the processing state of the function block. After completion or abortion of processing (due to an error), DONE is set to TRUE for one cycle. This output always has to be considered together with output ERR. If ERR is TRUE, an error occurred. In this case, the error number can be read at output ERNO.
ERR (error)
Data type: BOOL
Output ERR indicates whether an error occurred during data reception. If ERR is TRUE, an error occurred. In this case, the error number can be read at output ERNO.
ERNO (error number)
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| WORD | 0 | ³ 0 | - |
Output provides an error identifier if an invalid value was applied to an input. ERNO always has to be considered together with the output ERR. The value output at ERNO is only valid if ERR is TRUE (see, error messages): Error Messages of the Function Block Libraries
ENERGY_SAVED (energy saved)
Data type: REAL, default value: 0, range: ³ 0, unit: kWh
Stores the energy saved.
Difference of the energy consumed, considering the pumps motor connected directly to the grid (DOL), compared to the using a drive to control the motor.
MONEY_SAVED (money saved)
Data type: REAL, default value: 0, range: ³ 0, unit: currency (e.g. Dollar, Euro)
Money saved is calculated by multiplying ENERGY_SAVED and TARIFF. Its unit is the same unit as TARIFF.
CO2_REDUCTION (CO:sub:2 reduction)
Data type: REAL, default value: 0, range: ³ 0, unit: t/kWh
Indicates the reduction in carbon dioxide emissions.
ENERGY_CONSUMED (energy consumed)
Data type: REAL, default value: 0, range: ³ 0, unit: kWh
Indicates the value of energy consumed in the monitoring duration. While input TOTAL_ENERGY indicates cumulative value of energy consumed.
EFF_INSTANT (instant efficiency)
Data type: REAL, default value: 0, range: ³ 0
Instant flow power efficiency of the system in m:sup:3/kWh.
EFF_HOUR (hourly efficiency)
Data type: REAL, default value: 0, range: ³ 0
Hourly flow power efficiency of the system in m:sup:3/kWh.
EFF_DAY (daily efficiency)
Data type: REAL, default value: 0, range: ³ 0
Daily flow power efficiency of the system in m:sup:3/kWh.
