EtherNet/IP Conformance Test
Conforms to A5.
EtherNet/IP Interface
10Base-T/100Base-TX
Auto Negotiation/Fixed Setting
Note 1. “Packets per second” is the number of communications packets that can be processed per second.
2. Large Forward Open (CIP optional specification) must be supported in order for 505 to 1,444 bytes to be used as the data size. Application is supported between CS/CJ-series PLCs.
When connecting to devices from other manufacturers, make sure that the devices support the Large Forward Open specification.
3. If the maximum number is exceeded, refreshing will require more than one CPU Unit cycle.
4. When changing parameters, however, the EtherNet/IP port where the change is made will be restarted. In addition, a timeout will temporarily occur at the other node that was
communicating with that port, and it will then recover automatically.
5. The EtherNet/IP port supports an IGMP client, so unnecessary multicast packets are filtered by using a switching hub that supports IGMP snooping.
