CJ2M-CPU3

@/-CPU1@/-MD21@

8

*7. The EtherNet/IP port is built into CJ2M-CPU3@ only.

*8. "Packets per second" is the number of communications packets that can be processed per second.

*9. If the maximum number is exceeded, refreshing will require more than one CPU Unit cycle.

*10.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.

*11.The EtherNet/IP port supports an IGMP client, so unnecessary multicast packets are filtered by using an Ethernet switch that supports IGMP

snooping.
