Data sending
Data is sent from the originator to the target.
Data can be sent when the connection type is Exclusive Owner.
■Sending data with the Cyclic trigger type
Set the trigger type to Cyclic in the connection settings to periodically repeat the sending of data.
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) on the RJ71EIP91 on the scanner side is
turned on, the connection open request is sent, and then a response is received from the EtherNet/IP device on the adapter
side.
2.
Sending data ((5) to (6) shown above)
If the connection is established normally, the originator 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.
