General

Definition
A technology cycle is a subprogram that is called in the action part of a synchronized action.
All language elements and system variables that are also used in the action part of a
synchronized action can be used in a technology cycle. In addition, there are also the
following language elements that may only be used within a technology cycle:
● Section "System variables for synchronized actions (Page 17)"
● Section "User-defined variables for synchronized actions (Page 57)"
● Section "Language elements for synchronized actions and technology cycles (Page 59)"
● Section "Language elements for technology cycles only (Page 66)"
● Section "Actions in synchronized actions (Page 67)"
End of program
The following commands are permitted as end of program:
Search path
When calling a technology cycle, the same search path is used as for subprograms and
cycles.

Multiple calls
If a condition is fulfilled again while the technology cycle is being executed, the technology
cycle is not restarted.
If a technology cycle is started because of a fulfilled
still fulfilled after completion of the technology cycle, then the technology cycle is started
again.
Behavior with non-modal synchronized actions
A non-modal synchronized action is always linked to the next main run block. If the execution
time of the technology cycle is longer than the processing time of the associated main run
block, the technology cycle is aborted with the block change.
