SYSMAC CJ-series EtherNet/IP Unit
CJ1W-EIP21
CSM_CJ1W-EIP21_DS_E_4_1
Introducing the New EtherNet/IP Unit.
More Than 180,000 Words of Tag
Data Link Capacity!
• EtherNet/IP is an industrial multivendor network that uses
Ethernet. Managed by the ODVA (Open DeviceNet
Vendors Association), it has open standards and is used
with a wide range of industrial devices.
• The EtherNet/IP Unit supports tag data links to enable
sharing data between devices at Ethernet nodes and a
message service for sending and receiving data when
required.
• The EtherNet/IP Unit supports the same FINS/UDP and
FINS/TCP functionality as Ethernet Units.
CJ1W-EIP21
Features
• Large-capacity tag data links are easily enabled by simply setting connections, with no programming required.
• Tag data links can be used to exchange data with up to 256 nodes over up to 256 connections.
• Up to 256 connections can be set per Unit with up to 722 words of data per connection, for a total of up to 184,832 words of link data.
(There is no limit to the data link capacity for the overall network.)
• Data concurrency is maintained within each connection (for up to 722 words).
• Tag data link settings can be changed for individual Units even while tag data links are being used on a network.
• Errors can be diagnosed using the Network Configurator, and system errors can be monitored with a wide array of status flags.

Note: 1. Always use a switching hub when using tag data links in the network.
2. If a repeater hub is used for EtherNet/IP tag data links (cyclic communications), the network's communications load will increase, data
collisions will occur frequently, and stable communications will be impossible.

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-series Units 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, 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.

Label showing IP address
A label that can be used to show the IP address and subnet mask is provided.
Ethernet connector
The network is connected with shielded twisted-pair cable.
