RemoteMSTPDevice
The BACnet RemoteMSTPDevice is a component which is responsible for servicing a physical device connected to the iSMA-B-AAC20 controller by the BACnet RS485 bus. Each device is represented by a unique BACnet Device ID. The component has a ping action available under right-click, which sends a test message to the device to check the device status (meaning Monitor ping requests). Ping requests are also generated at the network-level, and the network’s monitor periodically pings (queries) devices. If any response from the device is received, including an exception response, it is considered a proof of communication. All data points which are to be read from or written to the device must be placed under the Device component.
Slots
The RemoteMSTPDevice component has the following slots:
- Status: component’s current status;
- Fault Cause: fault cause description;
- Enabled: enable/disable servicing device;
- Device Name: read-only, the BACnet device name (read from device);
- Location: read-only, the BACnet device location description (read from device);
- Description: read-only, additional description label (read from device);
- Device ID: the BACnet device address (In Discover action this field is filled automatically).
Device Discover
The BACnet MS/TP master supports device discovering. This action is available under right-click on the RemoteMSTPNetwork component. The Discovering process is shown in the Status slot. At the end of this process a Discover folder will be created and all found devices will be placed there.
Adding BACnet MS/TP Device Manually
The BACnet RemoteMSTPNetwork allows also to add the device manually (offline). To do this, add the BACnet Device component under the RemoteMSTPNetwork, enter the BACnet Device ID number.
Set Enable to true and if the device is online, the status OK should appear. If the device status is down, check the connection and use the ping action to refresh the status.
