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) 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.
3.
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).
4.
Sending data ((6) 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 is turned on.
5.
Completion of Application Trigger
After the data send processing completes, 'Application Trigger Completion (Class1)' (Un\G27040 to Un\G27055) on the
RJ71EIP91 turns 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.
• When 'Application Trigger operating specification request' (Un\G16631) is set to 10H (output data is not
transmit automatically at the RPI interval), the request is not transmit automatically. Therefore, when
Application Trigger is used, transmit the request within the monitoring time of send/receive timeout.
external device cannot receive the request within the monitoring time of send/receive timeout, the timeout is
detected and the connection is disconnected. In this case, a re-connection establishment is required to
send data again.
*1 Be sure to receive the request on the external device within the monitoring time of send/receive timeout.
Transmit the request in a shorter period of time than the monitoring time of send/receive timeout, considering the transmission
processing time and data transmission time in a module.
*2 Transmit the request from Consumer side (originator) to the target because the heartbeat needs to be sent even "Output Size" is 0
bytes.
