Same as before, go to the Device Library and Drop the Target(Tag).
Enter the Tag Name as My64BytesTags and enter 64 in the Size field.
Done!RJ71EIP91 Producer Tags is configured.
We can overview all conections and their number form the tools.
Add Comsumer Tags
Now we can start to create the Comsumer Tags.
MyOmronTags
MyOmronTags that occupies 2 Bytes will create in this step.
go to Device LibraryからEthernet/IP Devices>Omron Corporation>Communication Adapter and Drop the NX-CSG320 Revision 2.6.
Enter the IP address of Omron NX-CSG320 and 192.168.250.19 is in my case.
Go to the Connection Tag>Remove the Default Connection.
Now we can add a new connection.
Select Input Only(Tag Type) as the Connection Type and OK.
Go to the General Tab and enter the Tag name.
The Consumer Tags that occupy 2 Bytes (MyOmronTags), so we will enter the Input Size is 2 Bytes, as Point to Point is the Input Mode. In other words, the RJ71EIP91 is now outputting data from a 2-byte Tag called MyOmronTags.
DY0
DY0 Tag is occupied with 64 Bytes.
Click the Add button from the same Connection as before to add a Connection.
Select Input Only(Tag type)>OK.
Open the Connections Tab, and enter the TagName is DY0 – with 64bytes Input size with Point to Point Input Mode.

Local Label
Let’s define the local variable in the program.
Code
Here is the code.
- Check if the module is ready.
- If there is an error in the module, apply a reset flag to automatically reset it.
- If the module is Ready, the communication set the request Flag to True.
- Finally, branch at CASE and if Case=3,4, use RJ71EIP91_Class1GetInputData_00A library to get Tag data. If Case=1,2, use RJ71EIP91_Class1SetOutputData_00A library to write Tag data.
