Data sending
Data is sent from Producer to Consumer.
■Sending data with the Cyclic trigger type
Set the trigger type to Cyclic in the connection settings to periodically repeat the sending of data.
CPU module
Device
(1) Turn on 'EtherNet/IP communication start request' (Y10).
(2) Connection open
(3) Response (normal)
(4) Transfer the stored data with a program.
(5) Send the stored data at the RPI interval.
(6) Sending data
(7) Store the data received at the RPI interval.
Data is sent with the Cyclic trigger type 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 Producer side
and the RJ71EIP91 on the Consumer side is turned on, a connection open request is received from the RJ71EIP91 on the
Consumer side, and then a response is returned by the RJ71EIP91 on the Producer side.
2.
Sending data ((5) to (7) shown above)
If the connection is established normally, Producer sends the data stored in 'Class1 Output Area' (Un\G196608 to
Un\G229375).
For the operation timing of EtherNet/IP communications, refer to the following.
