Call of Technology Cycles

Definition
A technology cycle is a sequence of actions that are executed sequentially in the
interpolation cycle. The actions listed in the Chapter "Actions in synchronized actions" can
be grouped together to programs. From the user's point of view, these programs are
subprograms without parameters.
Parallel processing in channel
Several technology cycles or actions can be processed simultaneously in the same channel.
These cycles and actions are processed in parallel in the channel in one interpolation cycle.
Various processing methods
With respect to processing sequence, the user must select the most suitable method from
the following options:
• Several actions in one synchronized action:
• Actions are grouped together to form a technology cycle:
Commands such as variable assignments in technology cycles are processed in one
interpolation cycle. Other commands (e.g. motion of a command axis, see Chapter "Starting
of command axes") last for several interpolation cycles. If the function is completed (e.g.
exact stop on positioning of axis), the next block is executed in the following interpolation
cycle.
Each block requires at least one interpolation cycle. If a block contains several single-cycle
actions, then these are all processed in one interpolation cycle. Fig. "Multiple technology
cycles" provides examples to indicate which actions are single-cycle and which are multi-
cycle.
Application
One possible application of technology cycles is to move each axis using a separate axis
program.
Programming
A technology cycle can be activated as a function of a condition in a modal/static
synchronized action.
End of program is programmed with M02 / M17 / M30 / RET.
Synchronized actions
Function Manual, 11/2006, 6FC5397-5BP10-2BA0
All actions are executed simultaneously in the interpolation cycle in which the condition is
fulfilled.
The actions in the technology cycle are processed sequentially in the interpolation cycle.
One block is processed in each interpolation cycle. A distinction must be made between
single-cycle and multi-cycle actions. A technology cycle is ended when its last action has
been executed (generally after several interpolation cycles have passed).
