Example with “Automatic”
counter type
Only available if the “Enable Clear” option has not been selected. As soon as the set
counter value is reached, the counter generates a pulse, the duration of which is twice the
cycle time (2 x Tcycle).
Pulses at the “C
K_DOWN” input reduce the internal count value at the block.
Figure 5-124 Example pulse diagram for “COUNTER” with “Automatic” counter type
Example with “Manual”
counter type
Only available if the “Enable Clear” option has been selected. As soon as the set counter
value is reached, the counter output is set to logic “1”. Output “Q” changes to logic “0” when
the “C
LEAR” input value is set to logic “1”.
Pulses at the “C
K_DOWN” input reduce the internal count value at the block.
Figure 5-125 Example pulse diagram for “COUNTER” with “Manual” counter type
Example with “Manual/Au-
tomatic” counter type
Only available if the “Enable Clear” option has been selected. As soon as the set counter
value is reached, the counter generates a pulse, the duration of which is twice the cycle time
(2 x Tcycle). When the “C
LEAR” input value is set to logic “1”, the counter is reset to “0”.
Pulses at the “C
K_DOWN” input reduce the internal count value at the block.
