Example:
Event occurs during a cyclic program execution (S1).
Event occurs during a pause (S2).
At the end of each spontaneous pass the cyclic pass is retriggered around the set cycle time.
In this case no exceeding of the cycle time is signaled.
As long as the events occur in a time-scale that is smaller than the cycle time, only spontane-
ous program passes take place. If the cycle time is set to
0 and the spontaneous program ex-
ecution to 1 , then only spontaneous program passes take place.
You find further details in the manual SICAM RTUs Common Functions System and Basic
System Elements, chapter "Automation", section "Restricted Open-/Closed-Loop Control
Function", "Internal Signal Processing"

5.2.1.5 System Information
By means of system variables the following information items can be evaluated in the control
logic:
•
System time
•
Processing time
•
Timeout (yes/no)
•
Number of program runs
You find further information on system variables in the Appendix A , Variables in the Instruction
List .
You find the description of the system variables in the manual SICAM RTUs Common Func-
tions System and Basic System Elements, chapter "Automation", section "Restricted
