Scaling EL3783
Scaling of the input data of current and voltage provided as inputs by EL3783 EtherCAT Terminals.
In the Beckhoff Information System you will find the documentation of the corresponding PLC function block FB_PMA_Scaling_EL3783.
In the Beckhoff Information System you will find the documentation of the TF3650 TwinCAT 3 Power Monitoring function with descriptions of the corresponding PLC library.
Configuration parameters
- Factor Current Transformer: Factor of the current trans former. This is calculated by dividing the input current by the output current.
- Autorange: Automatic range selection activated in the EtherCAT Terminal.
Input values
- Input Voltage 1 ... Input Voltage 3: Raw values of the voltage of the individual phases.
- Input Current 1 ... Input Current 3: Raw values of the current of the individual phases.
- Hc Range Active: TRUE if the Auto-Range mode is active on the terminal.
- Hc Range: The current measuring range information of the EL3783 in Auto-Range mode.
- Use 5A range (optional): If the value is TRUE, the 5A measuring range of the EL3783 is used. If it is FALSE, the 1 A measurement range is used. Cannot be combined with Auto-Range mode.
Output values
- Output Voltage 1 ... Input Voltage 3: Scaled voltage values of the individual phases.
- Output Current 1 ... Input Current 3: Scaled current values of the individual phases.
