Class3 message communications with the server function is performed according to the following procedure.
1.
Connection establishment ((1) to (3) shown above)
The connection is established when 'EtherNet/IP communication start request' (Y10) of the RJ71EIP91 on the server side is
turned on, a connection open request is received from the EtherNet/IP device on the client side, and then a response is
returned.
2.
Command request acceptance and response ((4) to (6) shown above)
If the connection is established normally, a command request is sent from the EtherNet/IP device with arbitrary timing.
When the RJ71EIP91 receives the command request from the EtherNet/IP device, the RJ71EIP91 executes the command
processing and returns the command response to the EtherNet/IP device.
For the operation timing of EtherNet/IP communications, refer to the following.
