Cascading technology cycles

Function
Up to 8 technology cycles can be processed switched in line. Several technology cycles can
then be programmed in one synchronized action.
Syntax
ID=1 WHEN $AA_IW[X]>50 DO TEC1($R1) TEC2 TEC3(X)
Sequence of execution
The technology cycles are processed in order (in a cascade) working from left to right in
accordance with the aforementioned programming. If a cycle is to be processed in ICYCON
mode, this delays all the subsequent processing actions. An alarm aborts all subsequent
actions.
10.5.6

Technology cycles in non-modal synchronized actions

Function
Technology cycles are also possible in non-modal synchronized actions.
If the processing time of a technology cycle is longer than the processing time of the
associated block, the technology cycle is aborted when the block is changed.
Note
A technology cycle does not prevent the block change.
10.5.7

Check structures (IF)

Function
IF check structures can be used in synchronized actions for branches in the processing
sequence of technology cycles.
Syntax
IF <condition>
$R1=1
[ELSE] optional
$R1=0
ENDIF
