This section describes how to design an EtherNet/IP system in the following
two cases.
(1) Establishing a new EtherNet/IP system
(2) Modifying an established EtherNet system
This section describes how to use the Network Configurator to construct a
new EtherNet/IP system by designing the new system and downloading the
parameters to the network devices.
Always use a switching hub when using tag data links. Select a switching hub
with the functions required for the communications being used in the network.
Refer to 2-2 Selecting the Network Devices.
1. Starting the Network Configurator
Start the Network Configurator.
Refer to ???7-2-1 Starting and Network Configurator.
2. Registering Devices
Use the Network Configurator to register devices in the EtherNet/IP net-
work.
Refer to ???7-2-3 Registering Devices.
3. Setting Device Parameters
Set the device parameters (communications settings such as tag data link
parameters, FINS/UDP settings, and FINS/TCP settings) for each device
in the network configuration.
Refer to ???7-2-4 Creating Tag Sets and ???7-2-5 Setting the Con-
nections with Target Devices.
4. Verifying the Network Bandwidth Being Used
The network's communications load capacity is called the bandwidth. Ver-
ify that the bandwidth used by the EtherNet/IP tag data links does not ex-
ceed the allowed network bandwidth.
If the bandwidth exceeds the allowed level, adjust the packet interval (RPI).
Refer to 2-3 Checking Bandwidth Usage and Adjusting the Packet In-
terval (RPI).
5. Calculating and Verifying the Maximum Response Time
Calculate the maximum response time of all of the tag data links, and verify
that the response time meets the required specifications. If the response
time does not meet the required specifications, evaluate and correct the
network configuration by taking steps such as dividing the network.
Refer to ???Section 11 Communications Performance and Communi-
cations Load.
6. Saving the Network Configuration File
Save the network configuration file with the completed design.
Refer to ???7-2-11 Saving the Network Configuration File.
