Figure 4: OR function without delay

Case 1: The actuator follows the ON and OFF signals that are active in the switch
object.
Case 2: The actuator follows the ON and OFF signals that are active in the logic
object.
Case 3: If the signals of the switch object and the logic object intersect each other, the
output is switched on by the first ON signal and switched off by the last OFF
signal sent.

2.1.3.2 OR Function with ON and OFF Delay

Note: The OR function with an ON and OFF delay reacts differently depending on the
manufacturer. The flow charts are therefore shown for various products.
