• Overflow SCT1.1:
The threshold value for the switching cycles counter SCT1.1 has been reached.
• Overflow SCT1.2:
The threshold value for the switching cycles counter SCT1.2 has been reached.
• Overload
• Underload
10.7.1 Switching cycle monitoring
The device stores the number of switching cycles on the switching channels SSC1.1 (counter SCT1.1)
and SSC1.2 (counter SCT1.2). Depending on the set counting condition, individual switching edges or
piston strokes (two switching edges) will be counted.
The counter value can be read via the IO-Link interface.
When using the IO-Link interface, a data bit is set when a set switching cycle threshold is reached. This
change of state applies for a defined hold time or until the counter is reset.
10.7.1.1 Configuring counters
The switching cycle counters SC1 and SC2 are configured separately.
Parameter Explanation
SC-EnhCtr_HoldTime. S1CT
SC-EnhCtr_HoldTime. S2CT
Hold time:
Duration of the changed switching status when reaching the switch-
ing cycle threshold in milliseconds.
Requirement: SC-EnhCtr_AutoReload. SCx = On.
SC-EnhCtr_AutoReload. SC1
SC-EnhCtr_AutoReload. SC2
Counter reset:
• OFF: The output switches when the switching cycle threshold is
reached. The counter continues counting until it is reset: Reset
counter to zero
21
.
• On: The output switches when the switching cycle threshold is
reached. The switching status remains active for the set hold time
SC-EnhCtr_HoldTime. SCx. Then the switching output is reset.
The counter continues to count during the hold time.
SC-EnhCtr_CountCondition. SC1
SC-EnhCtr_CountCondition. SC2
Count condition:
• Rising: The counter only adds up switching cycles when changing
from low to high (0 → 1).
• Falling: The counter only adds up switching cycles when changing
from high to low (1 → 0).
• Both: The counter adds up the switching cycles on both edges.
Note the logic.
SC-EnhCtr_Threshold. SC1
SC-EnhCtr_Threshold. SC2
Switching cycle threshold:
Number of switching cycles at counter SCx at which a switching sig-
nal is triggered or the SCx bit is set.
Tab.1: Parameters for switching cycle monitoring
