– ‘p_br_front’ rises to 30. As ‘p_br_front’ is > 20 (condition is TRUE), the condition ‘max
(p_br_front, p_br_front_mx)’ in the THEN window is triggered. The condition sets the
bigger value as new value for ‘p_br_front_mx’. As ‘p_br_front’ (30) is bigger than
‘p_br_front_mx’ (10), the new value for ‘p_br_front_mx’ is set to 30.
– Although ‘p_br_front’ falls to 25, the value of ‘p_br_front_mx’ stays 30. This is caused
by the THEN-condition, because p_br_front_mx’ (30) is still bigger than
p_br_front’ (25).
– ‘p_br_front’ rises to 40. As ‘p_br_front’ (40) is bigger than ‘p_br_front_mx’ (30), the new
value for ‘p_br_front_mx’ is set to 40.
– As ‘p_br_front’ falls below 20, the IF-condition turns to FALSE. Now the OTHERWISE-
condition is triggered. Because the condition ‘p_br_front_mx’ sets the value of
‘p_br_front_mx’ and the value is already set to 40, nothing changes.
– When ‘p_br_front’ rises to 40, the IF-condition changes to TRUE again and triggers the
THEN-condition. Now the reset value (10) is used for ‘p_br_front_mx’ in the THEN-
condition.
– The new value of ‘p_br_front_mx’ is 40 because 40 is bigger than 10.
9.3 Conditional Channels
– Logical operations on measurement channel(s)
– If-Else structure with reset
– Logical result
– Result can be used as input source for alarm display elements and further calculations
in the whole RaceCon project.
