Bacnet Object Configuration View
An Object is a data item such as a temperature, a switch value or
actuator state. Objects can be thought of as point parameters.
The two categories of Objects supported by BacnetSpyder are:
- Fixed_Dropable: Fixed_Dropable Objects can be used while
creating an application logic and only its Internal Data Type can be edited. Fixed
Dropable Objects can also be displayed on the wiresheet.
- Custom: Custom Objects are the objects that are
created while creating an application logic. They can be created, edited, and deleted
based on your requirements.
The Bacnet Spyder supports the following object types.
- AVI - Analog Value Input
- AVO - Analog Value Output
- AV Setpoint - Analog Value Setpoint
- BVI - Binary Value Input
- BVO - Binary Value Output
- BV Setpoint - BinaryValue Setpoint
- MVI - Multi-state Value Input
- MVO - Multi-state Value Output
- MV Setpoint - Multi-state Value Setpoint
The configured objects are mapped to the Function Block memory
space to be used by any Function Block. Each Object is configured with a name.
