For details, refer to the CPU Unit’s Operation Manual.
The transmission delay time depends on the baud rate set for the EtherNet/IP
Unit or built-in EtherNet/IP port, as shown in the following table. (There may
be additional delays due to the other devices in the network, such as switch-
ing hubs.)
The following table shows the CPU Bus Unit service cycle, which depends on
the CPU Unit’s CPU processing mode setting.
For details, refer to the CPU Unit’s Operation Manual.
The following table shows the CPU Bus Unit service processing time, which
depends on the CPU Unit’s CPU processing mode setting.
