10.5 Technology cycles
Function
As an action in synchronized actions, you can invoke programs. These must consist only of
functions that are permissible as actions in synchronized actions. Programs structured in this
way are called technology cycles.
Technology cycles are stored in the control as subprograms.
It is possible to process several technology cycles or actions in parallel in one channel.
Programming
The following rules apply when programming technology cycles:
● End of program is programmed with
M02/M17/M30/RET.
● All actions specified in
ICYCOF can be processed in one cycle without waiting cycles within
one program level.
● Up to 8 technology cycles can be queried one after another per synchronized action.
● Technology cycles are also possible in synchronized actions that are effective block-for-
block (non-modal).
● Both
IF check structures and GOTO, GOTOF and GOTOB jump instructions can be
programmed.
● The following applies to blocks with
DEF and DEFINE instructions:
–
DEF and DEFINE instructions are read over (ignored) into technology cycles.
– These result in alarm messages if the syntax is incorrect or incomplete.
– They can be read over without an alarm message without being set-up themselves.
– They are taken into full consideration with value assignments as part program cycle.
Parameter transfer
Parameter transfer to technology cycles is possible. Both simple data types which are
transferred as formal "Call by Value" parameters and default settings which take effect when
technology cycles are called up are taken into account. These are:
● Programmed default values when no transfer parameters are programmed.
● Standard parameter with initial values.
● Non-initialized actual parameters with a default value are transferred.
Sequence
Technology cycles are started as soon as their conditions have been fulfilled. Each line in a
technology cycle is processed in a separate IPO cycle. Several IPO cycles are required to
execute positioning axes. Other functions are executed in one cycle. Blocks are sequentially
executed in the technology cycle.
If actions that are mutually exclusive are called up in the same interpolation cycle, the action
that is called up from the synchronized action with the higher ID number becomes active.
