BACnet Schedule Objects

The iSMA BACnet can share schedules created in the application over the BACnet network. The schedules can be read and written over the BACnet network. The iSMA-B-AAC20 controller serves two types of the BACnet objects schedules:

• Boolean schedule: shares the Boolean schedule in the BACnet network;
• Numeric schedule: shares numeric (float) schedule in the BACnet network.

To share the schedule objects in the BACnet network, first the schedule must be created in the application (for information see the iSMA-B-AAC20_plat manual).

Next, the corresponding type of the BACnet schedule object component must be placed under the BACnet LocalDevice network.

WARNING! In the BACnet device the same object type should have the unique BACnet Name and Object ID values.

Then, make the link between the schedule component to the corresponding BACnet component. If everything is ok, in the Status slot should appear “Ok” label, and from this moment trend should be enable to read/write by the BACnet network.

Schedule Special Events

Using the BACnet protocol, the user can send special events to the BACnet schedules (like holidays, etc.). During these events, the schedule can have a defined value, different than the one during normal working.

One schedule can have up to 10 special events with one value per day. It means that during the special event the user can define one value (in the hour range from 00.00 to 23.59). Another event that day will set up the default value at schedule output.
