6.3 Confirmation of Network Information
Network Condition about the IP Address, Subnet Mask, Gate Way, Mac Address of GN-9371/2/3 can be
checked, or set up from the following process below by using the IO Guide Pro Tool under Modbus RTU, and
Modbus TCP protocol types.
* IP Address : Also known as an "IP number" or simply an "IP," this is a code made up of numbers separated
by three dots that identifies a particular computer on the Internet. Every computer, whether it be a Web
server or the computer you're using right now, requires an IP address to connect to the Internet. IP
addresses consist of four sets of numbers from 0 to 255, separated by three dots.
* Subnet Mask : A subnet mask is a number that defines a range of IP addresses that can be used in a
network. (It is not something you wear on your head to keep subnets out.) Subnet masks are used to
designate sub networks, or subnets, which are typically local networks LANs that are connected to the
Internet. Systems within the same subnet can communicate directly with each other, while systems on
different subnets must communicate through a router.
* Gate Way : A gateway is either hardware or software that acts as a bridge between two networks so that
data can be transferred between a number of computers.
* Mac Address : A MAC address is a hardware identification number that uniquely identifies each device on a
network. The MAC address is manufactured into every network card, such as an Ethernet card or Wi-Fi card,
and therefore can’t change.
