In this article, we will explain how to set up an EtherNet/IP + Tag Set connection between OMRON NX CPUs.
By utilizing Tag Sets, you can combine multiple global variables into a single EtherNet/IP Tag, which helps with structuring data, saving Tag count, and managing variables.
Now, let’s enjoy FA!
Implementation
In this article, settings are required for both NX102-9000 and NX502-1500.
NX1 Side
First, configure the NX1 side.
EtherNet/IP Port
Please configure the IP settings for the EtherNet/IP Port of the NX102-9000 main unit.
Structures
Next, click Data → Data Types to create a structure.
In this article, we define a UNION data type that can share a memory OFFSET.
Global Variables
Now let’s define global variables. Click Data → Global Variables.
Define global variables using the UNION structure defined earlier.
Then, set output variables to Output and input variables to Input.
EtherNet/IP Settings
Next, to configure the EtherNet/IP connection for NX102-9000, click Tools > EtherNet/IP Connection Settings.
In this article, we will use Port 2 of NX102-9000, so select Port 2 > right-click > Edit.
This is the EtherNet/IP settings screen in Sysmac Studio.
Create New Tag Set
To create a new Output Tag, open the Output tab → right-click → Create New Tag Set.
Done! A new Tag Set has been added.
Next, enter the Tag Set name.
Next, right-click on the Tag Set you just added → click Create New Tag.
Done! A Tag row has been added.
Now, let’s enter the Output variable added earlier under Global Variables.
You can see that the Tag named EIP_PIS_Status occupies 4 Bytes.
Transfer to Controller
After completing the EtherNet/IP settings, transfer the EtherNet/IP settings to NX502-1500 using Transfer to Controller.
Download
Next, transfer the entire project to NX502-1500 using Transfer > To Controller.
NX5 Side
Next, configure the NX5 side.
In Sysmac Studio, multiple CPUs can be combined into a single project.
First Login
When connecting to a brand new NX502-1500 from Sysmac Studio, you will be prompted to set up a Username and Password. Configure these and transfer them to the CPU.
Done!
EtherNet/IP Port
Next, configure the IP settings for the EtherNet/IP Port of the NX502-1500 main unit.
Global Variables
Now let’s define global variables. Click Data → Global Variables.
Define the global EtherNet/IP input data variable and set it to Input.
EtherNet/IP Settings
Next, to configure the EtherNet/IP connection for NX5, click Tools > EtherNet/IP Connection Settings.
Right-click the port using EtherNet/IP → Edit.
This is the EtherNet/IP connection settings screen in Sysmac Studio.
Register All Variables
Register Input/Output variables in the program to the EtherNet/IP network using the “Register All” button.
Adding NX102-9000
Next, add the EtherNet/IP connection for NX102-9000 in Sysmac Studio.
Node Address
Set Node Address to the IP address of the NX102-9000.
Model Name
Please set Model Name to NX102-9000.
Revision
Set Revision to 2.
Result
Finally, click the Add button to add NX102-9000.
Done!
Creating a New Connection
Next, create a new EtherNet/IP connection and set the Input Variable to match the Tag Set name on the NX1 side.
Transfer to Controller
After completing the EtherNet/IP settings, transfer the EtherNet/IP settings to NX102-9000 using Transfer to Controller.
Download
Next, transfer the entire project to NX102-9000 using Transfer > To Controller.
Result
A blue indicator light is lit for Target Node Status on the NX5 side, indicating that communication has been established.
Data from NX1 has been successfully transferred to NX5 via EtherNet/IP!
