Ethernet Port Usage
The Flex-Net FACP has built in network capability which can connect to larger networks via
Ethernet. This capability allows for further annunciation and control of the system through the
Open Graphical Network (OpenGN) software, the integrated web server and Building
Automation and Control Networks (BACnet) software. It is recommended that connections
only be made to secure networks.
2.1 Wiring/IP Settings
An Ethernet connection can be found in each node on the main board (MD-871A). The port is
labelled P7 and can be found in the bottom left corner of a mounted board. An Ethernet cable
can be connected from here directly to the required network through a router or switch.
Each node connected directly to the network requires its own Internet Protocol (IP) address to
identify it. The IP address must be unique to the node and it must not be used by any other
terminal or device on the network. This information is configured in the job file using the
configurator. Refer to the figure below.
In the configurator select the node from the Job Details tree on the left to display the Network
Node Info on the right. Each node requires a separate reserved static IP. Enter the IP address,
subnet mask and default gateway to complete the required networking information. The
subnet mask is a number that combined with the IP address identifies which network segment
the node resides on. The default gateway is the address of the router that the node connects
to. Contact your network administrator if you require assistance setting up a reserved static IP
or inputting correct values for the subnet mask and default gateway.
To allow an application, such as OpenGN or BACnet explorer, to connect and receive events
ensure that the check box "Run TCP Services" is selected.
To actively monitor the Ethernet connection for connectivity scroll down and select the
"Supervise Ethernet Connection" check box. This will create a trouble event if the node does
not detect an Ethernet connection.
