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.
