How To Setup Data Exchange between NX-Safety I/O And NX-I/O Units with the NX-EIC202


This is a quick start tutorial on how to get the data exchange between NX-Safety and Standard NX-I/Os (Analog, Digital and Temperature units) with a NX-EIC202 (Ethernet/IP Coupler) using Sysmac Studio.

Hardware Configuration

For this tutorial an example is given using the following hardware configuration:

How to configure the data exchange between NX-Safety and Standard NX-IO

This paragraph describes step-by-step how to use Sysmac Studio in order to configure NX-Safety I/O and Standard NX-I/O using NX-EIC202.

Step 1: Start a new Sysmac Studio project.

Step 2: Select "Slave Terminal" in the Category selection and "EtherNet/IP Coupler" as Device.

Step 3: Add several different NX I/O, Safety IN / OUT, Analog IN / OUT and Digital IN / OUT as shown in the image below.

Step 2: Go to the Safety section in Sysmac Studio.

Step 3: In the safety section you have direct access to all NX-Safety Modules. 

Step 4: To get access to all other standard NX I/O's you must first create the variables to be used in the Safety program. You can create the variables in the Exposed Variables tab.

Step 5: Connect the variables to the NX I/O devices by open the Standard I/O section and choose the connected NX Device and which Linked Port It should use.


Step 6: Now you can create your safety project with standard NX I/O devices as shown below.


Specifications for I/O Data Allocations in Slave Terminals

The following limitations apply to I/O data allocations for the entire Slave Terminal:

 Item  Input data  Output data
 Number of I/O entry mappings  255  255
 EtherNet/IP maximum I/O connection size  504 bytes 504 bytes 
 Allocatable I/O data points  Maximum of 4,000 points total for both inputs and outputs

The content of this article is based on Sysmac Studio version 1.11.
