CJ-series EtherNet/IP Units Operation Manual for NJ-series CPU Unit (W495)
The following examples explain how to calculate the packet intervals (RPIs) in the following network
configuration.
•
Connections:
Example:Twenty CJ1W-EIP21 Units are connected to the network.
Each device has one 100-word tag for transmission and nineteen 100-word tags for recep-
tion, so that the Units exchange data mutually. By default, the packet intervals (RPIs) are
set to 10 ms for all of the connections. The devices’ IP addresses range from
192.168.250.1 to 192.168.250.20.
