| Target node PLC's operating and error information, and registered/normal target node information | ||
| CPU Bus Unit System Setup | Not used. | |
| Non-volatile memory within EtherNet/IP Unit (See note.) | The following settings are stored in the EtherNet/IP Unit's non-volatile memory. Note: Unlike the regular Ethernet Units, the CPU Bus Unit Setup Area in the CPU Unit is not used for these settings. 1. Unit setup (communications settings for the EtherNet/IP Unit, such as the IP address, DNS server settings, host name, baud rate, FINS/UDP settings, and FINS/TCP settings) 2. Tag data link settings (device parameters) | |

| Number of cascade connections | There is no limitation when a switching hub is used. | |
| Current consumption (Unit) | 410 mA max. at 5 V DC | |
| Weight | 171 g max. | |
| Dimensions | 35 × 130 × 101 mm (W × H × D) | |
| Other general specifications | Other specifications conform to the general specifications of the CS-series | |
Note:If tag data links are being used, use 100Base-TX. Otherwise, 10Base-T can be used, but this is not recommended.
Communications Specifications
| Item | Specifications | ||
| CIP service | Tag data links (Cyclic communications) | Number of connections | 256 |
| Packet interval (refresh cycle) | 0.5 to 10,000 ms (in 0.5-ms units) Can be set independently for each connection. (Data is refreshed over the network at the preset interval and does not depend on the number of nodes.) | ||
| Allowed communications bandwidth per Unit | 6000 pps (See note 1.) | ||
| Number of tag sets | 256 | ||
| Tag types | CIO Area, DM Area, EM Area, Holding Area, and Work Area | ||
| Number of tags per connection (= 1 tag set) | 8 (7 tags when the tag set contains the PLC status) | ||
| Maximum link data size per node | 184,832 words | ||
| Maximum data size per connection | 252 words or 722 words (See note 2.) Note: Data synchronicity is maintained within each connection. | ||
| Number of registrable tag sets | 256 (1 connection = 1 tag set) | ||
| Maximum size of 1 tag set | 722 words (The PLC status uses 1 word when the tag set contains the PLC status.) | ||
| Maximum number of tags that can be refreshed per CPU Unit cycle (See note 3.) | Output/Transmission (CPU to EtherNet/IP): 19 Input/Reception (EtherNet/IP to CPU): 20 (See note 4.) | ||
| Data that can be refreshed per CPU Unit cycle (See note 3.) | Output/Transmission (CPU to EtherNet/IP): 7,405 words Input/Reception (EtherNet/IP to CPU): 7,405 words | ||
| Changing tag data link parameters during operation | Supported (See note 5.) | ||
| Multicast packet filter function (See note 6.) | Supported | ||
| Explicit messaging | Class 3 (connected) | Number of connections: 128 | |
| UCMM (unconnected) | Number of clients that can communicate at one time: 32 max. Number of servers that can communicate at one time: 32 max. | ||
| CIP routing | CS1W-EIP21 | ||
| FINS service | FINS/UDP | Supported | |
| FINS/TCP | 16 connections max. | ||
| EtherNet/IP conformance test | Conforms to A5 | ||
| Ethernet interface | 10BASE-T or 100BASE-TX Auto Negotiation or fixed settings | ||
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.
| Service | Protocol | Port number | Remarks |
| Tag data links | UDP | 2222 | Fixed value |
| Class 3, UCMM | TCP/UDP | 44818 | |
| DNS | UDP | 53 | |
| FINS/UDP service | UDP | 9600 | Port numbers in the Unit Setup can be changed with the CX-Programmer. |
| FINS/TCP service | TCP | 9600 | |
| FTP | TCP | 20, 21 | |
| SNTP | UDP | 123 | |
| SNMP | UDP | 161 | |
| SNMP trap | UDP | 162 |
Network Configurator Requirements
The Network Configurator Ver. 3.0 or higher is a software package designed for building, setting, and controlling a multi-vendor EtherNet/IP Network using OMRON's EtherNet/IP. It is included in CX-One version 3.0. The Network Configurator provides the following functions for building, setting, and controlling EtherNet/IP.
| Item | Specification | ||
| Operating environment | CXONE-AL[][]C-V3/CXONE-AL[][]D-V3 | ||
| Network connection method | CS1/CJ1 | CJ2 | |
| Serial interface | CPU Unit's Peripheral or RS-232C port | CPU Unit's USB or RS-232C port | |
| Ethernet interface | EtherNet/IP Unit's Ethernet port | CPU Unit's Ethernet port EtherNet/IP Unit's Ethernet port | |
| Location on Network | A single node address is used (only when directly connected to EtherNet/IP). | ||
| Number of Units that can be connected to Network | A single Network Configurator per Network (More than one Configurator cannot be used in the same system.) | ||
| Main functions | Network control functions | The Network configuration can be created and edited regardless of whether the Network Configurator is online or offline. The Network configuration can be read from a file or the network. | |
| Configuration functions | The EDS files used by the Network Configurator can be installed and deleted. | ||
| Supported file formats | Configurator network configuration files (*.nvf) Configuration files (*.ncf) created using the Network Configurator for EtherNet/IP (version 2) can be imported by selecting External Data - Import from the File Menu. | ||
Caution: In the interenst of product improvement, specifications are subject to change without notice.
