*1. Includes the End Cover, and does not include projecting parts.
*2. Includes the End Cover. The weight of the End Cover is 82 g.
*3. Includes the SD Memory Card. The NX Unit power consumption to NX Units is not included.
*4. This is the inrush current value when the power supply turns ON after it has been OFF.
The inrush current may vary depending on the operating condition and other conditions. Therefore, select fuses, breakers, and external power supply devices that have enough margin in characteristic and capacity, considering the condition under which the devices are used.
Especially when you turn the power ON/OFF through a switch inserted to the external DC power supply, cycling power ON-OFF-ON within one second will cause the inrush current of approx. 30 A/0.3 mA to occur since the inrush current limiter circuit fails to limit the current.
*5. The amount of current that can be passed constantly through the terminal. Do no exceed this current value when you use a through-wiring for the Unit power supply.
*6. The actual configurable number can be calculated as follows: 254 - <Number of CIP Safety connections configured> - <Number of FSoE connections configured>

EtherNet/IP conformance test Conforms to CT14
Ethernet interface 10BASE-T or 100BASE-TX
Auto negotiation or fixed settings

*1. If tag data links are being used, use 100Base-TX.
*2. Here, pps means “packets per second” and indicates the number of packets that can be processed in one second.
*3. To use a data size of 505 bytes or higher, the system must support a large forward open (an optional CIP specification).
The CS, CJ, NJ, and NX-series Units support a large forward open, but before connecting to nodes of other companies, confirm that those devices also support it.
*4. If more than 40 tag sets are registered in total, the Tag Data Link, Too Many Tag Sets Registered (840E0000 hex) event will occur.
*5. Because the built-in EtherNet/IP port is equipped with an IGMP client (version 2), unnecessary multicast packets can be filtered out by an Ethernet switch that supports IGMP Snooping.
*6. The built-in EtherNet/IP port uses the TCP/UDP port numbers shown in the following table.
Do not set the same port number for more than one TCP/UDP service.
