Fig. 51 Differentiated list of functions
Trigger Type Selection Meaning
Level: High (H; 1) or Low (L; 0) State is present at the input for a longer period.
H High, is live and logical 1
L Low, logical 0
Low level As long as a low level < V
+
/2 ±5 % is present at the input, the
stored function is executed.
High level As long as a high level > V+/2 ±5 % (max. 30 V) is present at
the input, the stored function is executed.
When the state changes from Low to High or from High to Low, signal edges occur. These are meaningfully
referred to as positive or negative edge-triggered.
Rising edge Change of state between L (< V
+
/2 ±5 %) to H (> V
+
/2 ±5 %). During this change, the
stored function is executed.
Falling edge Change of state between H (> V
+
/2 ±5 %) to L (< V
+
/2 ±5 %). During this change, the
stored function is executed.
