How can we get a Communication failure status from the connected 3rd party Bacnet IP device in PFC200 controller.Its a Gateway application on PFC200 to read data from BACnet device and send it to SCADA over Modbus TCP. Customer require a Communication failure status of the connected Bacnet Device. Any possibilities?

When you create the Client Mapping in the BACnet Configurator, be sure to enable the “Connection Monitoring” option for each Client Mapping element. You must then also export the controller object as size Medium or Large back to Codesys. If enabled (and utilizing a Medium or Large object model), the Status Flags property of each object will indicate a Fault if the network connection to the external device drops out.

Hello Adam,  
thank you for the comment , it worked well.  
i get a xAlarm and xFault status , when i remove the connection from the connected Bacnet device. i am not sure whats the difference between the Alarm and fault, both seems to be having the same behaviour.
