Configure technology objects
The properties of a technology object on a S7-1200 CPU can be configured in two ways.
● In the Inspector window of the programming editor
● In the configuration editor
The properties of a technology object on a S7-300/400 CPU can only be configured in the
configuration editor.
Inspector window of the programming editor
In the Inspector window of the programming editor you can only configure the parameters
required for operation.
The offline values of the parameters are also shown in online mode. You can only change
the online values in the commissioning window.
To open the Inspector window of the technology object, follow these steps:
1. Open the "Program blocks" folder in the project tree.
2. Double click the block (cyclic interrupt OB) in which you open the instruction of the SW-
controller.
The block is opened in the work area.
3. Click on the instruction of the SW-controller.
4. In the Inspector window, select the "Properties" and "Configuration" tabs consecutively.
For each technology object, there is a specific configuration window in which you can
configure all properties.
To open the configuration window of the technology object, follow these steps:
1. Open the "Technology objects" folder in the project tree.
2. Open the technology object in the project tree.
3. Double-click the "Configuration" object.
Icons in the area navigation of the configuration and in the Inspector window show additional
details about the completeness of the configuration:
The configuration contains default values and is complete
.
The configuration exclusively contains default values. With these default values the use of the technology object is
possible without further changes.
The configuration contains user-defined or automatically adjusted values and is complete
All input fields of the configuration contain valid values and at least one default setting was changed.
The configuration is incomplete or faulty
At least one input field or a collapsible list contains no or one invalid value. The corresponding field or the drop-down
list box has a red background. When clicked, the roll-out error message indicates the cause of the error.
The properties of a technology object are described in detail in the section for the technology
object.
