Data is sent from Producer to Consumer.

Producer Tag
'Class1 Output Area'
(Un\G7536640 to
Un\G7721471)
 Write the Class1 tag communications connection settings.
 When the tag names and data sizes of the Producer Tag and Consumer Tag match, a connection opens.
 Send the data stored on the Producer side at the RPI interval.
Data communications procedure
1.
Connection settings
Set a connection in "EtherNet/IP Configuration". ( Page 117 "EtherNet/IP Configuration" window)
2.
Establishing a connection
'EtherNet/IP communication in process' (X10) turns on at the following timing, and a connection starts to open.
• A value other than 0 is set for 'EtherNet/IP communication start request' (Un\G7340096).
• When the EtherNet/IP communication automatic start function is enabled, initialization after power-on is completed.
3.
Sending/receiving data
When a connection is opened normally, data is sent/received at the RPI interval as follows.
• The data sent by the target is stored in 'Class1 Input Area' (Un\G7348224 to Un\G7533055).
• The data set in 'Class1 Output Area' (Un\G7536640 to Un\G7721471) of the originator is sent to the target.
Connection settings
The following settings are required when performing tag communications using the CC-Link IE TSN Plus module as the
originator.
• Check the tag name set for the target
• Use "EtherNet/IP Configuration" to configure the scanner settings for the CC-Link IE TSN Plus module based on the tag
name set for the target
The following settings are required when performing instance communication using the CC-Link IE TSN Plus module as the
target.
• Use "EtherNet/IP Configuration" to configure the adapter settings for the CC-Link IE TSN Plus module
• Set it so communication is performed for the tag name set in the originator device.
