BaObject handling
Almost all existing TcHmiBa controls can process a BaObject. The handling of symbols in the BaSite-Extension is basically identical to that of the ADS-Extension.
Handling
A simple example should give you an idea of the possible applications inside and outside a UserControl. For this purpose, the TcHmiBa controls SensorAnalog and Textblock are linked to a greatly reduced variant of an analog sensor in a TcHmi project.
The structure of the PLC is as follows:

Symbol mapping direct
Linking the symbol from the BaSite-Extension directly to the attribute BaObject of a TcHmiBa control.

Symbol mapping via UserControl parameters
The UserControl in this example has the parameters BaObject01 and BaObject02 of type Symbol to pass through the symbols from the BaSite-Extension.
![]() | Nature and source of the hazard The Symbol data type is more performant for the TcHmiBa controls. |

Due to the data type, it is no longer possible to navigate in the object when creating the binding.
However, deeper objects can still be reached by manually extending the symbol.
One parameter
Symbol for parameter BaObject01:
IFP01::Top::Children::Sample::Children::Sensor01

Several parameters
Symbol for parameter BaObject01:
IFP01::Top::Children::Sample::Children::Sensor01
Symbol for parameter BaObject02:
IFP01::Top::Children::Sample::Children::Sensor01::Children::MV
