Uniquely identify this FB using up to 20 alphanumeric characters.
Output Type
Set whether the physical analog output supplies a voltage or current signal.
Options:
• Volts: the output supplies a voltage signal
• Milliamps: the output supplies a current signal
Scale Low
Set the desired value for the output in electrical units (mA DC or VDC) when the input to the
block equals the Range Low setting. Scale Low and Range Low are the coordinates of a point
on the line that relates the input to the scaled output.
Consult the hardware specifications for the signal range supported by the specific hardware.
Range: -100.0 to 100.0 mA DC (typically 0 mA DC or 4 mA DC)
-100.0 to 100.0 VDC (typically 0 VDC)
Scale High
Set the desired value for the output in electrical units (mA DC or VDC) when the input to the
block equals the Range High setting. Scale High and Range High are the coordinates of a point
on the line that relates the input to the scaled output.
Consult the hardware specifications for the signal range supported by the specific hardware.
Range: -100.0 to 100.0 mA DC (typically 20 mA DC)
-100.0 to 100.0 VDC (typically 1, 5, or 10 VDC)
Range Low
Set the value for the input to the block at which the Scale Low setting is the desired output
value. When using the output to retransmit an analog signal, this is typically the low end of
the range being retransmitted. When using the output for control, this is typically 0%.
Range: -99,999.000 to 99,999.000
Range High
Set the value for the input to the block at which the Scale High setting is the desired output
value. When using the output to retransmit an analog signal, this is typically the high end of
the range being retransmitted. When using the output for control, this is typically 100%.
Range: -99,999.000 to 99,999.000
