Data sending with Change of State is performed according to the following procedure.
1.
Setting of EtherNet/IP Configuration Tool
Set the following items in the setting of EtherNet/IP Configuration Tool.
• Set the trigger type to "Change of State".
• Set "Inhibit Time Mode". (When setting "Inhibit Time Mode" to "Custom", set "Inhibit Time".)
2.
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.
3.
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.
4.
Sending data ((6) to (7) shown above)
Data stored in 'Class1 Output Area' (Un\G196608 to Un\G229375) is sent when the specified Inhibit Time has elapsed after
'Application Trigger Acceptance (Class1)' (Un\G27024 to Un\G27039) on the RJ71EIP91 on the Producer side is turned on.
5.
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.
• For the operation timing of EtherNet/IP communications, refer to the following.
Page 137 EtherNet/IP communication start request (Y10)
• For the operation timing of data sending using the Application Trigger, refer to the following.
Page 148 Application Trigger (Class1) (Un\G27008 to Un\G27055)
• When Application Trigger or Change of State is used, data will be sent automatically if no data was sent
during the period from the last sending of data to the end of the RPI.
• To send data only by turning off and on 'Application Trigger Request (Class1)' (Un\G27008 to Un\G27023),
set 'Application Trigger operating specification request ' (Un\G16631) to 10H.
• When Change of State is used, data is sent when the specified Inhibit Time has elapsed regardless of the
setting of 'Application Trigger operating specification request' (Un\G16631).
• During Class1 tag communications, heartbeat is sent by turning off and on 'Application Trigger Request
(Class1)' (Un\G27008 to Un\G27023) when 'Application Trigger operating specification request'
(Un\G16631) is set to 10H.
