Typical Object Values

Following are descriptions of the five objects related to
each feedback loop:

Analog Input (AI) – Used to collect analog-to-digital values
from the photodiode input. Manually entering values into
this object has no effect on the PI feedback loop.

Setpoint Analog Variable (AV) – Used to set the desired
amount of light in a given area.

Proportional Band Analog Variable (AV) – The value given to
the proportional component for the PI feedback loop.
Incorrect values for this object could cause the output to
oscillate. This value is set to 100 in the default database.

Reset Rate Analog Variable (AV) – The value given to the
integral component for the PI feedback loop. Incorrect
values for this object could cause the output to oscillate.
This value is set to 5 in the default database.

Output Analog Variable (AV) – The voltage sent to the
output. Manually entering values into this object has no
effect on the PI feedback loop.
