■Sending data with the Application Trigger or Change of State trigger type
Set the trigger type to Application Trigger or Change of State in the connection settings to send data at a given timing.
Use this function in situations such as when it is temporarily necessary to communicate at an interval that is shorter than the
communication cycle in a system that has a long RPI interval.

(1) Turn on 'EtherNet/IP communication start request' (Y10).
(2) Connection open
(3) Response (normal)
(4) Transfer the stored data with a program.
(5) Turn on 'Application Trigger Request (Class1)' (Un\G27008 to Un\G27023).
(6) Sending data
(7) Store the data received at the timing of Application Trigger or Change of State.
Data is sent with the Application Trigger trigger type according to the following procedure.
1.
Setting of EtherNet/IP Configuration Tool
Set the trigger type to "Application" in the setting of EtherNet/IP Configuration Tool.
2.
Setting of buffer memory
Set 'Application Trigger operating specification request' (Un\G16631). ( Page 145 Application Trigger operating
specification request (Un\G16631))
3.
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.
4.
Application Trigger request ((5) shown above)
During communications with the RJ71EIP91 on the Consumer side, 'Application Trigger Request (Class1)' (Un\G27008 to
Un\G27023) of the RJ71EIP91 on the Producer side is turned on.
5.
Sending data ((6) to (7) shown above)
'Application Trigger Acceptance (Class1)' (Un\G27024 to Un\G27039) on the RJ71EIP91 on the Producer side is turned on
and the data stored in 'Class1 Output Area' (Un\G196608 to Un\G229375) is sent.
6.
Completion of Application Trigger
After the data send processing has completed, 'Application Trigger Completion (Class1)' (Un\G27040 to Un\G27055) on the
RJ71EIP91 on the Producer side is turned on.
