Additional Information
If you select Multi-cast Connection for the connection type in the connection settings on the
Network Configurator, multicast packets are used. If you select Point to Point Connection for
the connection type, multicast packets are not used.
If required tag data link performance cannot be achieved with the Ethernet switch, re-evaluate the
overall network configuration and take necessary measures such as selecting a different Ethernet
switch or splitting the network.
The following sections show how to check the device bandwidth used by the tag data links in the de-
signed network, and how to set appropriate values.
15-2-1
Checking Bandwidth Usage for Tag Data Links
The Network Configurator can display the bandwidth to be actually used for tag data links at each
built-in EtherNet/IP port, based on the connections set in the network configuration.
The device bandwidth used for tag data links can be checked by clicking the
Detail Button in the
Usage of Device Bandwidth Area at the bottom of the Network Configuration Window.
Item Description
# The IP address of the device.
Comment A description of the device. The comment is displayed below the device icon.
The model number of the device is displayed by default.
Usage of Capacity (without
Multicast Filter) The usage rate of allowable tag data link bandwidth for the device is given.
Bandwidth used/Allowable tag data link bandwidth
The values outside parentheses are for when multicast filtering is used.
The values inside parentheses are for when multicast filtering is not used.
Mbit/s (without Multicast Fil-
ter) The network bandwidth used by the device for tag data link communications is
given.
The values outside parentheses are for when multicast filtering is used.
The values inside parentheses are for when multicast filtering is not used.
Usage of IP multicast ad-
dresses The number of multicast IP addresses actually used by the device for commu-
nications is given.
Total usage of IP multicast ad-
dresses The number of multicast IP addresses used in the entire network is given. This
value is used to estimate the number of multicast filters required for a switch.
