(a) In the IF Condition, when AI
value:
Assuming the Deadband value is set to be 2 mA, and the
following statements are defined in the related logic Rule:
IF AI>10mA, THEN DO=ON, ELSE DO=OFF, that
means, when AI receives a signal that exceed 10mA, the
DO channel will change to ON immediately, however,
when the AI channel value drops and becomes lower than
10mA, the DO channel will not change back to OFF
immediately until the value reaches 8mA (10mA minus
the Deadband value 2mA), as shown in the following
figure.

(b) In the IF Condition, when AI
value:
Assuming the Deadband value is set to be 2 mA, and the
following statements are defined in the related logic Rule:
IF AI<10mA, THEN DO=ON, ELSE DO=OFF, that
means, when AI receives a signal which is lower than
10mA, the DO channel will change to ON immediately,
however, when the AI channel value exceed 10mA, the
DO channel will not change back to OFF immediately
until the value reaches 12mA (10mA plus the Deadband
value 2mA), as shown in the following figure.
