Global Variables
10.1.
To see the Global Variables in the Multiview Explorer, expand Programming, expand Data, and
double-click "Global Variables". NOTE: Important Global Variables are identified in Appendix B.
10.2.
In this application there are a total of 12 global variables used for ID-40 EtherNet/IP
communications. Six global variables, highlighted in blue in the image below, are used to store each
ID-40 input assembly. Each global variable used to store an EtherNet/IP input assembly must have
Network Publish set to Input.
10.3.
Six global variables, highlighted in yellow in the image above, are used to store each ID-40 output
assembly. Each global variable used to store an EtherNet/IP output assembly must have Network Publish
set to Output.
10.4.
Once the global variables to be used for EtherNet/IP communications have been created, the project
must be downloaded to the NJ/NX controller.

Before starting this process, SYSMAC Studio should be configured to communicate using Ethernet connection
via hub. If this has not been completed, follow steps starting at 7.1, found in the section "Omron NJ/NX
Controller Ethernet Connection via a Hub".
