## Display microblocks Display microblocks communicate directly with BACnet objects, and can be used to integrate BACnet devices into the WebCTRL® system. They can be referenced on graphics, allowing any vendor's BACnet equipment to be integrated into the system's interface. Display microblocks differ from other microblocks: They are not downloaded into a controller; they are modeled in the system database. They cannot be used in a control program's control logic, although they can be the source of alarms. A single microblock can read from or write to multiple properties in a BACnet object.
| BACnet Modeled Analog Input This microblock reads the properties from a BACnet Analog Input object in any BACnet device on the network and makes these values available in the WebCTRL® or Field Assistant system.
| BACnet Modeled Binary Input This microblock reads the properties from a BACnet Binary Input object in any BACnet device on the network and makes these values available in the WebCTRL® or Field Assistant system.
| BACnet Modeled Multi-State Input This microblock reads the properties from a BACnet Multi-State Input object in any BACnet device on the network and makes these values available in the WebCTRL® or Field Assistant system. Multi-State microblocks are used to indicate values that have more than two discrete states.
| BACnet Modeled Analog Output This microblock reads the properties from a BACnet Analog Output object in any BACnet device on the network and makes these values available in the WebCTRL® or Field Assistant system.
| BACnet Modeled Binary Output This microblock reads the properties from a BACnet Binary Output object in any BACnet device on the network and makes these values available in the WebCTRL® or Field Assistant system.
| BACnet Modeled Multi-State Output This microblock reads the properties from a BACnet Multi-State Output object in any BACnet device on the network and makes these values available in the WebCTRL® or Field Assistant system. Multi-State microblocks are used to indicate values that have more than two discrete states.
| BACnet Modeled Analog Value This microblock reads the properties from a BACnet Analog Parameter Value object in any BACnet device on the network and makes these values available in the WebCTRL® or Field Assistant system.
| BACnet Modeled Binary Value This microblock reads the properties from a BACnet Binary Value Parameter object in any BACnet device on the network and makes these values available in the WebCTRL® or Field Assistant system.
| BACnet Modeled Multi-State Value This microblock reads the properties from a BACnet Binary Value Parameter object in any BACnet device on the network and makes these values available in the WebCTRL® or Field Assistant system.
| BACnet Modeled Calendar This microblock defines a standardized object used to describe a list of calendar dates, which might be thought of as holidays, special events, or simply as a list of dates and makes these values available in the WebCTRL® or Field Assistant system.
| BACnet Modeled Trend This microblock reads trend data from other objects in any BACnet device on the network and makes these values available in the WebCTRL® or Field Assistant system.
| BACnet Modeled Schedule This microblock defines a standardized object used to describe a periodic schedule that may recur during a range of dates, with optional exceptions on arbitrary dates. The Schedule object also serves as a binding between these scheduled times and the writing of specified values to specific properties of specific objects at those times.
| BACnet Modeled Event Enrollment This microblock defines an event and provides a connection between the occurrence of an event and the transmission of a notification message to one or more recipients.
| BACnet Modeled Notification Class This microblock defines a standardized object that represents and contains information required for the distribution of alarm notifications within BACnet systems.
| BACnet Modeled Program This microblock defines a standardized object whose properties represent the externally visible characteristics of an application program and makes these characteristics available in the WebCTRL® or Field Assistant system.
| BACnet Modeled Device This microblock defines a standardized object whose properties represent the externally visible characteristics of a BACnet device and makes these characteristics available in the WebCTRL® or Field Assistant system.
### To integrate using Display microblocks If Display microblocks will provide the functionality you need, you must address the Display microblocks in your control program to retrieve data from the BACnet points of interest. To retrieve data from BACnet objects using Display microblocks: Get network, object, device, and address information from the vendor of the BACnet device. If this information is not supplied, you can discover BACnet networks, devices, and objects. In the EIKON® application, create a control program with a Display microblock for each property you are interested in. NOTE Each Display microblock must match the BACnet object type it references. For example, to reference a BACnet analog input, use a BACnet Modeled Analog Input microblock. In each microblock, type the BACnet device's Device Instance number in the Device Alias field, then set the Object Instance to match the BACnet Object ID of the BACnet object it references. TIPS In EIKON®, use Edit > Third-Party BACnet Addresses with discovered BACnet information to set the Object Instance for a display object. To create a re-usable program, you can use the Device alias microblock. See the BACnet Integration Guide.
