#### To set up a BACnet/IP connection in the WebCTRL® interface Using a BACnet/IP connection and an Ethernet Network Interface Card, the WebCTRL® server can speak BACnet/IP over an Ethernet network. On the System Configuration tree, select Connections. On the Configure tab, select BACnet/IP Connection. If the Status column shows: Connected, click Disconnect. Stopped or Design Mode, go to step 4. Set up the fields as needed for that connection. See tables below. Click Accept. If running the WebCTRL Server (not WebCTRL Design Server) application, select the BACnet/IP Connection, then click Start.
Field or button | Notes
--- | ---
Server IP Address | Type the server's IP address. The IP address and subnet mask must also be set on the server's network connections page. NOTE If the server has more than 1 NIC, use the IP address of the interface connected to the controllers.
Server IP Subnet Mask | For default IP addressing, type `255.255.255.0`. For custom IP addressing, type the subnet mask provided by the facility network administrator.
BACnet Port | Type `47808` unless you need to communicate with a third-party device using a different port for BACnet communication or your IT administrator specified a different port.
Disable Field Alarms | Select if you do not want to retain incoming alarms on this connection. Typically this box might be checked during start-up then cleared for normal operation.
Poll Interval | How often the WebCTRL® application checks the communication status of the peer caching router. If it cannot communicate with the router, the WebCTRL® application generates a Dead Module Timeout alarm.
Foreign Device | If the WebCTRL® server is on an IP network segment that does not have an Automated Logic® controller serving as a BBMD, select Force Registration. See Setting up BBMDs.
Register with Device | If you selected Force Registration in the previous field, select the BBMD on a remote IP network from which the WebCTRL® server will receive BACnet/IP broadcasts.
Network Node | Specify which network the WebCTRL® server is physically connected to. This is primarily used to specify which ARCNET network the ARCNET card is connected to. This is also used to specify which BACnet/IP network the WebCTRL® server is on if there are multiple BACnet/IP network nodes with different network numbers in your system.
Tuning Parameters | Notes
--- | ---
Comm Timeout | Amount of time, in milliseconds, that is allowed before retrying a transmission on the network if a required acknowledgment is not received.
Comm Attempts | The number of times to try a transmission on the network.
Do Sync | Amount of time, in milliseconds, allowed for the WebCTRL® application to complete a communication task such as downloading to a controller or reading trends from a controller.
Register FD Interval | Amount of time, in seconds, that is allowed before the WebCTRL® application notifies a BBMD that the WebCTRL® server is a foreign device to that BBMD. If the re-registration does not occur within this time, the BBMD will delete the WebCTRL® server from its list.
