Rules for processing
–
The "write parameters" command record is always processed in one cycle and contains the start
of the next command.
–
The priority of the record sequences depends on the index of the data record in which the record
sequence was created. Record sequences in data records with a smaller index have priority over
record sequences in data records with a larger index. If conditions in multiple record sequences
return the value "true" simultaneously, the record sequence in the data record with the smaller
index is effective.
Timing
Start condition “Interrupt”
The current command (here record A) is interrupted immediately and the newly addressed command
(here record B) is then executed immediately.
