•
For instantaneous protection functions.
•
Binary I/O and circuit breaker control supporting the fast protection
functions.
•
The task starts on data change given by the analog signal scanning
•
10 ms
•
For time delayed protection functions, monitoring functions and fast
control applications like disconnector control.
•
The task is started by the end trigger of the 5 ms task
•
100 ms and 200 ms
•
For all other tasks mainly control and supervision functions
•
The task is started periodically by the clock and the end trigger of the 20 ms
task
The combination Execution Order, Instance Number is predefined by ABB. Mainly
for basic logic function blocks like for example AND, OR, a set of combinations
spread over the full range of execution orders is available. This gives the possibility to
select a combination which fits to the execution order range needed in that application
part.
Application configuration cycle time and execution order organization
The application execution within the 630 series products is organized in four time
classes, see

IEC09000740 V1 EN
Figure 36:
ACT: Possible MainApplication cycle times
For the same time point, faster cycle times are executed first.
A function block that is placed after a function block in the execution
flow must have the same or a higher cycle time and/or execution order.
