BACnet Elevator Example

This project was designed as an example of a BACnet IP server that implments Elevator groups, lifts, Escalator objects using C# and the CAS BACnet stack.

The server device has a fixed set of BACnet objects:

Elevator group (1000) - This elevator group contains only escalators.
- Escalator A (1001)
- Escalator B (1002)
Elevator group (2000) - This elevator group contains only lifts.
- Lift C (2001)
- Lift D (2002)
- Double deck lift
  - Lift E Top deck (2003)
  - Lift F Bottom deck (2003)
Lift G (2005) - This lift does not belong to a elevator group. Has two doors (Front and Rear)
Escalator H (1003) - This escalators does not belong to a elevator group
Positive integer value (1) - This is the machine room ID for Elevator group (1000)
Positive integer value (2) - This is the machine room ID for Elevator group (2000)

CAS BACnet Stack Elevator groups, lifts, Escalator functions

The specific function in the CAS BACnet stack for adding or manupliating the Elevator groups, lifts, Escalator object types.

AddElevatorGroupObject

Adds an Elevator Group Object. The device must be added first before this function can be called. The Elevator Group Object references various Lift or Escalator objects. If adding escalators or lifts to an Elevator Group Object, users must add the Elevator Group object first.

bool BACnetStack_AddElevatorGroupObject(
    const uint32_t deviceInstance, const uint32_t objectInstance,
    const uint32_t machineRoomId, const uint8_t groupId, const bool isGroupOfLifts,
    const bool supportLandingCallStatus)

deviceInstance [IN] - The instance number of the device that owns this Elevator Group Object.
objectInstance [IN] - The instance number of this Elevator Group Object.
machineRoomId [IN] - The instance number of the Positive Integer Value Object whose present value property represents the Machine Room ID. If the Positive Integer Value Object does not exist, this function will create it.
groupId [IN] - The group ID for this Elevator Group object.
isGroupOfLifts [IN] - A flag that sets the Elevator Group object to be a group of Lift Objects (true) or Escalator Objects (false).
supportLandingCallStatus [IN] - A flag to enable the Landing Calls and Landing Call Control properties.

return True if successful, false if failed.

AddLiftOrEscalatorObject

Adds a Lift or Escalator Object. The device must be added first before this function can be called. If adding to an Elevator Group Object, the Elevator Group object must be created first.

bool BACnetStack_AddLiftOrEscalatorObject(
    const uint32_t deviceInstance, const uint16_t objectType, 
    const uint32_t objectInstance, const uint32_t elevatorGroupInstance,
    const uint8_t groupId, const uint8_t installationId)

deviceInstance [IN] - The instance number of the device that owns this Lift or Escalator Object.
objectType [IN] - The object type of this object. Must be either Lift or Escalator.
objectInstance [IN] - The instance number of this Lift or Escalator Object.
elevatorGroupInstance [IN] - The instance number of the Elevator Group Object that this Lift or Escalator Object belongs to. If none exists, use 4194303 to specify that this Lift or Escalator Object is not part of an Elevator Group Object.
groupId [IN] - The groupId assigned to this Lift or Escalator Object.
installationId [IN] - The installationId assigned to this Lift or Escalator Object. If this Lift or Escalator Object belongs to an Elevator Group Object, it must have a unique installationId among all other Lift or Escalator Objects in the Elevator Group Object.

return True if successful, false if failed.

SetLiftHigherLowerDeck

Sets the HigherDeck and LowerDeck properties of the Lift Object. If the HigherDeck and LowerDeck properties have not been enabled for this Lift Object, then this function will enable them. This function is used to specify a Lift Object as a Multi-Deck Lift. If the Lift Object is the highest deck, then set the higherObjectInstance to 4194303. If the Lift Object is the lowest deck, then set the lowerObjectInstance to 4194303.

bool BACnetStack_SetLiftHigherLowerDeck(
    const uint32_t deviceInstance, const uint32_t objectInstance,
    const uint32_t higherDeckObjectInstance, const uint32_t lowerDeckObjectInstance)

deviceInstance [IN] - The instance of the device that contains the Lift object.
objectInstance [IN] - The instance of the Lift object to update.
higherDeckObjectInstance [IN] - The instance of a Lift object that is a higher deck to this Lift object. If this Lift Object is the highest deck, then set this to 4194303.
lowerDeckObjectInstance [IN] - The instance of a Lift object that is a lower deck to this Lift object. If this Lift Object is the lowest deck, then set this to 4194303.

return True if successful, otherwise false.

SetLiftOrEscalatorEnergyMeterRef

Sets the EnergyMeterRef property of a Lift or Escalator object. If the EnergyMeterRef property has not been enabled for this Lift or Escalator object, then this function will enable it.

If a Lift object already has the EnergyMeter property enabled and if the energyMeterRefObjectInstance is not set to 4194303, then the CAS BACnet Stack will use a value of 0.0 for the Energy Meter propery. Note: The above only applies to Lift objects, not Escalator objects

From the Spec: If the Energy_Meter_Ref property is present and initialized (contains an instance other than 4194303), then the Energy_Meter property, if present, shall contain a value of 0.0.

bool BACnetStack_SetLiftOrEscalatorEnergyMeterRef(
    const uint32_t deviceInstance, const uint16_t objectType,
    const uint32_t objectInstance, const bool energyMeterRefUseDevice,
    const uint32_t energyMeterRefDeviceInstance, const uint16_t energyMeterRefObjectType,
    const uint32_t energyMeterRefObjectInstance)

Alarms and Events

Use the following functions to enable alarms and events for Lifts and Escalator objects.

AddNotificationClassObject

First, add a Notification Class object. The Notification Class object contains all the information of how to handle event notifications.

bool BACnetStack_AddNotificationClassObject(
    const uint32_t deviceInstance, const uint32_t objectInstance, 
    const uint8_t toOffNormalPriority, const uint8_t toFaultPriority, const uint8_t toNormalPriority,

AddRecipientToNotificationClass

Once the Notification Class object has been created, the next step is to add a recipient to the Notification Class. A recipient is the BACnet Device that will receive the notifications as well as the days and times that it can receive them.

This gets added to an existing Notification Class Object, therefore, a Notification Class Object must exist before this function can be called.

bool BACnetStack_AddRecipientToNotificationClass(
    const uint32_t deviceInstance, const uint32_t notificationClassInstance, const uint8_t validDays, 
    const uint8_t fromTimeHour, const uint8_t fromTimeMinute, const uint8_t fromTimeSecond, const uint8_t fromTimeHundrethSecond, 
    const uint8_t toTimeHour, const uint8_t toTimeMinute, const uint8_t toTimeSecond, const uint8_t toTimeHundrethSecond,

recipientMacAddressLength [in] - The number of bytes of the macAddress. If BACnet IP, this should be 6.

EnableAlarmsAndEventsForObject

After at least one recipient has been added, it is time to enable alarms and events for each object that will support intrinsic alarming. To start this process, call the EnableAlarmsAndEventsForObject function to setup some preliminary alarm and event settings.

The object and the notification class object must exist before calling this function, otherwise the function will return false.

bool BACnetStack_EnableAlarmsAndEventsForObject(
    const uint32_t deviceInstance, const uint16_t objectType, const uint32_t objectInstance, const uint32_t notificationClassInstance, 
    const uint8_t notifyType, const bool enableToOffNormalEvent, const bool enableToFaultEvent, const bool enableToNormalEvent, const bool enableEventDetection)

Set up the intrinsic event and fault algorithms

After alarms and events have been enabled on the object, enable either the intrinsic event algorithm or the instric fault algorithm or both. The type of event or fault algorithm to use intrinsically will be determined by the ObjectType.
Since this example only uses Lifts and Escalators, then they will use the following algorithms:

Event Algorithm: ChangeOfState monitoring the PassengerAlarms property
Fault Algorithm: FaultsListed monitoring the FaultSignals property

For other intrinsic algorithm/object combinations, please refer to the CAS BACnet Stack - Alarms and Events pdf manual.

To enable these algorithm, use the functions described below:

SetIntrinsicChangeOfStateAlgorithmBool

To enable the intrinsic ChangeOfState event algorithm, use the following function. Note: the object must exist first and must have called the EnableAlarmsAndEventsForObject function before calling this one.

bool BACnetStack_SetIntrinsicChangeOfStateAlgorithmBool(
    const uint32_t deviceInstance, const uint16_t objectType, const uint32_t objectInstance, const bool alarmValue, 
    const uint32_t timeDelay, const bool useTimeDelayNormal, const uint32_t timeDelayNormal, const bool enable)

SetFaultOutOfRangeAlgorithmReal

To enable the intrinsic FaultsListed fault algorithm, use the following function. Note: the object must exist first and must have called the EnableAlarmsAndEventsForObject function before calling this one.

bool BACnetStack_SetFaultOutOfRangeAlgorithmReal(
    const uint32_t deviceInstance, const uint16_t objectType, const uint32_t objectInstance, const float faultLowLimit, const float faultHighLimit, const bool enable)

objectType [in] - The object type of the object for alarms and events.
objectType [in] - The object instance of the object for alarms and events.

Alarms and Events Callbacks

Some alarm and event functionality requires callback functions.
As of version 3.26.0 of the CAS BACnet Stack, the only Alarm and Event service that can use a callback is the following:

AcknowledgeAlarm

CallbackAcknowledgeAlarm

The CallbackAcknowledgeAlarm function is a callback function that a user implement and registers with the CAS BACnet Stack to authorize alarm acknowledges and to log them. This callback is called when the CAS BACnet Stack receives an AcknowledgeAlarm BACnet message.

The primary use of this callback is to validate acknowledgement source, to determine if it is authorized to acknowledge alarms. Users can also use this callback to log the acknowledges.
