This windows form application simulates an heating/cooling room controler. See the Readme file in the application directory.

• Send a Whois to all devices on the net
• Get back all the Iam responses
• Read Present_Value property on the object ANALOG_INPUT:1 provided by the device 1026
• Write Present_Value property on the object ANALOG_OUTPUT:0 provided by the device 4000

• Send a Whois to all devices on the net
• Get back all the Iam responses
• Advise to OBJECT_ANALOG_INPUT:1 provided by the device 1026, for 60 secondes
• Write on the console each notification

• Can send reponses to WhoIs query : own device id is 2000
• Can send responses to ReadProperty/ReadPropertyMultiple
• Write on the console each Alarm or Event received (broadcast or unicast)

• Send an Iam message : own device id is 1234
• Can send reponses to WhoIs query
• Offers three objects OBJECT_DEVICE:1234, OBJECT_ANALOG_INPUT:0, OBJECT_ANALOG_VALUE:0
• Only OBJECT_ANALOG_VALUE:0.PRESENT_VALUE can be writen
• OBJECT_ANALOG_INPUT_0.PRESENT_VALUE changes continously: PRESENT_VALUE = OBJECT_ANALOG_VALUE_0.PRESENT_VALUE * Sin (w.t)

• BBMD services on a simple device server with only one Device Object
• Foreign devices accepted
• Tested with
• Wago 750/830 (vendor Id 222)
• Newron DoGate (vendor Id 451)
• Sauter EY-AS521 (vendor Id 80)
• Also running on a Raspberry Pi on Linux/Mono

Shows another way, much complex than the original one in DeviceStorage.cs file (without the Xml descriptor also) to write a server. Each Bacnetobject is a object in the C# code. So a class must be written for each Bacnet object type, but this give the possibility to have a complex behaviour in objects code. Shows also dynamic creation/destruction of objects by a remote client. Actual objects types are :

• Device
• Structured View
• Analog Input, Analog Value, Analog Output (With Intrinsect reporting)
• Digital Input, Digial Value, Digital Output
• Multistates Input, Multistates Value, Multistates Output (With Intrinsect reporting)
• Characters String
• File
• Trendlog
• Notification Class
• Schedule
• Calendar

Objects persistance could be achieved with serialization

This application is similar to BasicServer, for Raspberry Pi with Mono. DeviceDescriptor.xml should be modify in order to access as your want the GPIO pins :

• OBJECT_BINARY_INPUT:x - GPIOX will be configured and used as an input
• OBJECT_BINARY_OUTPUT:x - GPIOX will be configured and used as an output
• PRESENT_VALUE will be apply to the output at the begining

When adding new objects, take care to add it also in the PROP_OBJECT_LIST of the DEVICE_OBJECT. In the original DeviceDescriptor.xml file one can found GPIO4 as input and GPIO7, GPIO8 as output. Also OBJECT_ANALOG_INPUT:0 get the CPU temperature. Mono should be installed (mono complete not mono runtime it's not enough !), and to start the code in sudo mode : sudo mono ./RaspberrySample.exe. DeviceDescriptor.xml must be in the application directory

Tested on a Raspberry Pi Model B. Similar code based on AnotherStorageImplementation. Run 24/24 acting also as a BBMD somewhere in France. Ready with small modifications (GPIO) for Intel/Edison, Texas/BeagleBone, and a lot of Linux plateforms with Mono installed.

A sample application that will transfer all present values from a given device, to a SQL database. (SQL CE Local DB.)

In theory each bacnet device should have object of type OBJECT_DEVICE with property PROP_OBJECT_LIST. This property should contain a list of all bacnet objects (ids) of that device. In this sample we detect bacnet device in local network and try to list its object ids by reading this property.
