Resolution is not particular to a type of input or output, but the driver handles analog and
digital (binary) inputs and outputs differently. To set these values appropriately, you
should understand how the driver uses them.
Resolution
Notes
Analog Input
(BAI)
The driver truncates the microblock's present value according to the
resolution.
EXAMPLE
If the calculated present value is 13.789 and you set the
Resolution
to 0.1, the control program uses 13.7 for any calculations
downstream from the microblock.
Analog Output
(BAO)
The driver truncates the wire input value to the microblock before
performing any scaling calculations.
EXAMPLE
If the wire input value is 13.789 and you set the
Resolution
to 0.1, the microblock uses 13.7 for any scaling
calculations.
Digital Inputs
and Outputs
N/A
Offset/Polarity is not particular to a type of input or output, but the driver handles analog
and digital (binary) inputs and outputs differently. To set these values appropriately, you
should understand how the driver uses them.
Offset/Polarity
Notes
Analog Input
(BAI)
Offset
value (positive or negative) adds a fine adjustment to a sensor
reading after all scaling for calibration.
EXAMPLE
If a sensor reads 74.9°F when the actual measured value
is 73.6°F, enter an
Offset
of –1.3 to calibrate the sensor to the
measured value.
Analog Output
(BAO)
You can use the
Offset
value (positive or negative) to calibrate an
output, but you generally do not need to. If used, the driver adds the
offset value to the wire input value before performing any scaling
calculations to determine the SE6166's output.
Digital (Binary)
Input (BBI)
Polarity
determines the microblock's present value when no signal is
received from the equipment.
When no signal is received from the equipment, if
Polarity
is set to:
normal
—present value is
off
reversed
—present value is
on
Digital (Binary)
Output (BBO)
Polarity
determines the SE6166's output based on the control
program's signal to the microblock.
When the control program's signal to the microblock is
on
, if
Polarity
is set to:
normal
—output is
on
reversed
—output is
off
NOTE
Regardless of
Polarity
, the output will be off if the SE6166
loses power.
