■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.
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) Turn on 'Application Trigger Request (Class1)' (Un\G27008 to Un\G27023).
(6) Sending data
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) 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.
4.
Application Trigger request ((5) shown above)
During communication with the EtherNet/IP device, the RJ71EIP91 turns on 'Application Trigger Request (Class1)'
(Un\G27008 to Un\G27023).
5.
Sending data ((6) shown above)
'Application Trigger Acceptance (Class1)' (Un\G27024 to Un\G27039) on the RJ71EIP91 is turned on and data stored in
'Class1 Output Area' (Un\G196608 to Un\G229375) is sent.
6.
Completion of Application Trigger
After the data send processing completes, 'Application Trigger Completion (Class1)' (Un\G27040 to Un\G27055) on the
RJ71EIP91 turns on.
