Ethernet/IP to OMRON PLC


Recommended Posts



Customer has to Ethernet/IP into an OMRON Safety PLC.

We have the EDS file (NX-EIC202), and can make the connection and get the Basic Parameters.

The issue is setting up the T2O    and O2T  Assemblies and Structs for the Global Variables.

( we have done Ethernet/IP Setups for Bar Code Scanners and MURR IO Blocks  sucesfully,)

We cannot locate the relevent data in the Omron Information.

Information, experiences would help.

Hello All.

The application Dan references above is using the Unistream as an Ethernet/IP master to an Omron NX-EIC202 Ethernet/IP Coupler, which has a Safety CPU and a number of safety I/O "slices" attached.

Parameters ended up as follows:

Input Assembly 100

Output Assembly 148

Configuration  199

Leave both Run Idle check boxes UN-Checked

Leave Config Size empty

Leave Multicast checkbox UN-Checked


I don't really know much about EDS files and I got fooled by viewing the EDS file for the NX-EIC202 in notepad, and after seeing the following, used 150 instead of 148 for the output ass'y

"Param2,Assem150,       $ O->T RPI, size, format
 ,Param1,Assem100,       $ T->O RPI, size, format"

Hope this helps anybody/everybody escape the time consuming trial & error approach I went through.
