1. Module
name:
There can be many ELC-CAENET modules on the network. You can set up a module
name for each module to identify the module when you need to use them.
2. Network
setup:
Enable dynamic IP (DHCP) or static IP..
A. IP
configuration:
There are 2 types of IP, static IP and DHCP.
Static IP: Preset or manually modified by the user.
DHCP: Automatically updated by a DHCP server. There must be a DHCP server in
the LAN.
IP
Explanation
Static
The user enters the IP address, subnet mask and gateway.
DHCP
DHCP server offers the IP address, subnet mask and gateway.
B. IP
address:
IP address is the location of the equipment on the network. Every device connected to
the network has to have a unique IP address. Incorrect IP address will result in
connection failure. The default IP for ELC-CAENET is 192.168.1.5.
C. Netmask:
Subnet mask is an important parameter for setting up the subnet, used for seeing if
the destination IP and the local equipment are in the same subnet. If not, the
equipment will send the packet to the gateway, and the gateway will send the packet
to another subnet. Incorrect setting may cause the destination equipment unable to
communicate to ELC-CAENET. To see if your setting is correct, conduct bitwise AND
operations between your IP and subnet mask and destination IP and subnet mask. If
the two values obtained are the same, the two IPs are in the same subnet. The default
subnet mask of ELC-CAENET is 255.255.255.0.
D. Gateway:
Gateway is the window for two different subnets, allowing the two ends in different
subnets to communicate. For example, if the LAN has to be connected to a WAN, it
will need a gateway to bridge the communication. The IP of the gateway has to be in
the same subnet as ELC-CAENET. The default gateway of ELC-CAENET is
192.168.1.1.
3. Timer
setting:
For setting up TCP connection idle time, Modbus time-out and minimum delay time for
every communication data. Please refer to the explanations on BR#11, BR#12, and
BR#13.
