Note (1) In this case, pps means “packets per second” and indicates the number of packets that can be processed in one second.

(2)To use 505 to 1,444 bytes as the data size, the system must support the Large Forward Open standard (an optional CIP specification). The SYSMAC CS/CJ-seriesUnits support this standard, but before connecting to nodes of other companies, confirm that those devices also support it.

(3)If the maximum data size is exceeded, the data refreshing with the CPU Unit will extend over two or more cycles.

(4)If status layout is selected in the user settings, the maximum number of tags that can be received is 19 tags.

(5)If parameters are changed in the EtherNet/IP Unit, however, the EtherNet/IP Unit will be restarted. When other nodes are communicating with the affected node, the communications will temporarily time out and automatically recover later.

(6)Because the EtherNet/IP Unit is equipped with an IGMP client (version 2), unnecessary multicast packets can be filtered by using a switching hub that supports IGMP snooping.

(7)The EtherNet/IP Unit uses the TCP/UDP port numbers shown in the following table.

Note (1) The Ethernet Address can also be checked with the CONTROLLER DATA READ command. For details, refer toAppendix E FINS Commands Addressed to EtherNet/IP Units or Built-in EtherNet/IP Ports.

(2)An IP address label is included with the EtherNet/IP Unit, so the user can record the user-setIP address and subnet mask on the label, and affix the label to the front of the Unit. When this label is affixed to the front of the Unit, it is easy to confirm the Unit’s IP address and subnet mask.

2-3-3Switching Hub Types

Unmanaged Layer 2 (L2)

Switching Hubs

Managed Layer 2 (L2)

Switching Hubs

These switching hubs use the Ethernet MAC address to switch ports. Ordinary switching hubs have this function. Switching hub functions and settings cannot be changed.

These switching hubs use the Ethernet address to switch ports. Switching hub functions and settings can be changed using special software tools for switching hubs running on a network node. Analytical data can also be collected. These switching hubs provide more-advancedfunctions that unmanaged layer 2 switching hubs.

28

Selecting the Network Devices

Section 2-3

2-3-4Switching Hub Functions

Multicast Filtering

QoS (Quality of Service) Function for TCP/UDP Port Numbers (L4)

This section describes the switching hub functions that are important when using an EtherNet/IP network. When using an EtherNet/IP Unit, set the following two functions.

Multicast filtering

QoS (Quality of Service) for TCP/UDP port numbers (L4)

Multicast filtering transfers multicast packets to the specific nodes only. This function is implemented in the switching hub as IGMP Snooping or GMRP. “Specific nodes” are nodes equipped with an IGMP client that have made transfer requests to the switching hub. (OMRON EtherNet/IP Units are equipped with an IGMP client.)

When the hub does not use multicast filtering, multicast packets are sent to all nodes, just like broadcast packets, which increases the traffic in the network. Settings must be made in the switching hub to enable this function.

There must be enough multicast filters for the network being used.

This function controls the priority of packet transmissions so that packets can be sent with higher priority to a particular IP address or TCP (UDP) port. The TCP and UDP protocols are called transport layer protocols, leading to the name L4 (layer 4) QoS function.

When tag data links and message communications are executed on the same network, tag data links can be sent at higher priority to prevent problems such as transmission delays due to message communications traffic and packet losses due to buffer overflow. Settings must be made in the switching hub to enable this function and give higher priority to tag data link packets.

Support for the above two functions is as follows for the different types of switching hubs.

Note If the Network Configurator is used to set the connection type in the connection settings to a multicast connection, multicast packets will be used. If the connection type is set to apoint-to-pointconnection, multicast packets will not be used.

2-3-5Precautions When Selecting a Switching Hub

The functions supported by the switching hub may affect tag data link transmission delays and the configuration. In addition, if the switching hub supports advanced functions, special settings are required for those functions.

29

Selecting the Network Devices

Section 2-3

When selecting a switching hub, it is necessary to consider whether the switching hub will be selected based on the kind and amount of communications that will be performed in the network or the kind of switching hub that you want to use. Refer to the following precautions when selecting a switching hub.

Refer to 10-2 Adjusting the Communications Load to estimate the communications load for tag data links.

Selecting the Switching Hub Based on the Types of Network Communications

Executing Tag Data Links

Only

Executing Tag Data Links

and Message

Communications

We recommend using an L2 switching hub without multicast filtering or an L2 switching hub with multicast filtering.

Using an L2 switching hub with multicast filtering prevents increased traffic due to unnecessary multicast packets, so the tag data links can operate at higher speed. If either of the following conditions exists, the amount traffic will be the same for both kinds of L2 switching hubs (with or without multicast filtering).

The tag data links are set to share the same data with all nodes in the network. (The multicast packets are transferred to all nodes in the network, just like a broadcast.)

The tag data link settings are all one-to-one(unicast) and multicast packets cannot be used.

If multicast filters are being used, settings must be made in the switching hub. There must be enough multicast filters for all of the networks being used.

We recommend using an L2 switching hub with multicast filtering and L4 QoS.

By setting tag data links for higher-prioritytransmission, it is possible to prevent problems such as transmission delays due to message communications traffic and packet losses due to buffer overflow. Settings must be made in the switching hub to enable this function and give higher priority to tag data link packets.

Special settings must be made in the switching hub when using the multicast filtering function and L4 QoS function.

Selecting the Switching Hub Based on the Hub’s Supported Functions

L2 Switching Hub without Multicast Filtering

L2 Switching Hub with Multicast Filtering

We recommend this kind of switching hub when only tag data links are executed and any of the following conditions is met.

The tag data links are set to share the same data with all nodes in the network. (The multicast packets are transferred to all nodes in the network, just like a broadcast.)

The tag data link settings are all one-to-one(unicast) and multicast packets cannot be used.

There is little traffic in the tag data links.

No special settings are required for an L2 switching hub without multicast filtering.

We recommend this kind of switching hub when only tag data links are executed and the following condition is met.

There are many 1:N links (where N represents some number of nodes in the network) in the tag data link settings, i.e., there are many multicast packets used, or there is heavy traffic in the tag data links.

Special settings are required for an L2 switching hub with multicast filtering. There must be enough multicast filters for the network being used.

30

Selecting the Network Devices

Section 2-3

L3 Switching Hub with Multicast Filtering and L4 QoS Functions

Note

We recommend this kind of switching hub when both tag data links and message communications are executed.

By setting tag data links for higher-prioritytransmission, it is possible to prevent problems such as transmission delays due to message communications traffic and packet losses due to buffer overflow. Settings must be made in the switching hub to enable this function and give higher priority to tag data link packets.

Special settings must be made in the switching hub when using the multicast filtering function and L4 QoS function. There must be enough multicast filters for the network being used.

(1)Ask the switching hub manufacturer for setting procedures for the switching hub.

(2)Install the switching hub so that its environmental resistance capabilities are not exceeded. Ask the switching hub manufacturer for information on the environmental resistance of the switch hub.
