Note
As per standard cybersecurity practices, the FloBoss
S600+ should reside on a closed Local
Area Network (LAN). If this is not possible, additional port blocking must be performed to
ensure the FloBoss
S600+ has no route to the Internet.
It
is recommended that the 2 network ports are on separate subnets.
3.1 Subnet Masks
The subnet mask can be used to further control the access to the network ports.
For example:
Network Port 1
•
IP Address = 192.168.102.2
•
Subnet = 255.255.255.128
•
Gateway = 192.168.102.127
These settings allow connection by devices in the range 192.168.10.1 to 192.168.102.126.
3.2 Network Cable Unplugged
By default, if a network cable is unplugged from an FloBoss
S600+ network port, the
FloBoss
S600+ stops responding to messages directed to the IP address of that network
port.
Within the cold start menu of the FloBoss
S600+ is an option to disable this functionality
(Located under NETWORK SETUP / WIRE UNPLUG GFC) meaning that if a network cable is
unplugged, the FloBoss
S600+ then routes all network traffic through the remaining
connected port. However, it is recommended that the smart switches within the network
perform this re-routing if required.
3.3 Network Configuration (06.30 and earlier)
Prior to binary.app 06.30a, only one gateway could be entered. This was entered for
network port 1 but the gateway would be used by the network port for which it was part
of the subnet.
In the example below, messages to an address outside of the 192.168.102.x range would
be sent to gateway 192.168.102.1 via network port 1 (the gateway is on network port 1
subnet).
Network Port 1
•
IP Address = 192.168.102.2
•
Subnet = 255.255.255.128
