5.4 Activating and deactivating technology objects
The user has configured and programmed a maximum configuration. Technology objects
which are not required (e.g. those assigned to deactivated DP slaves or IO devices) can be
deactivated without restarting during operation.
The required technology objects (together with the DP slaves or IO devices to which they are
assigned) can also be activated during operation.
This has the following advantages:
● The processor performance is concentrated on the activated technology objects. The
● The system cycle clocks do not have to be dimensioned for calculating all the technology
● A single project is suitable for various machine configurations; changes to the machine
● A default setting can be specified in the project as to which technology objects are active
Note
Licenses are required for all axes of the maximum configuration.
System functions
● _activateTo (Page 79)
● _deactivateTo (Page 79)
● _getStateOfTo (Page 85)
The syntax of these system functions is described in detail in the "System Functions/Variables
Devices" List Manual (reference list) and in the online help (see index).
Note
Technology objects are often assigned to the distributed I/O (DP slave, IO device); therefore,
please note the information in Procedure for deactivating and activating components
(Page 86).

objects present in the maximum configuration, but only for the maximum number of
simultaneously active technology objects. They can then generally be selected with shorter
times: This increases the time resolution and reduces any response times; motion control
is improved.
