In this article, we will use OMRON’s NX1+SL5500 and connect it to Euchner’s MGB-L2B-EIA-R-136508 and CIP Safety. We will also use OMRON’s standard Safety FB for the safety program.
Come on, let’s enjoy FA.
Foreword
Thank you from the bottom of my heart for visiting my technical blog and YouTube channel.
We are currently running the “Takahashi Chris” radio show with Full-san (full＠桜 八重 (@fulhause) / X) which I deliver every Wednesday night.
Sharing, not hoarding, technical knowledge
We publish technical information related to factory production technology and control systems for free, through blogs and videos.
With the belief that “knowledge should be accessible to everyone,” we share practical know-how and real-world troubleshooting cases from our own field experience.
The reason we keep it all free is simple: to help reduce the number of people who struggle because they simply didn’t know.
If you’ve ever thought:
- “Will this PLC and device combination actually work?”
- “I’m having trouble with EtherCAT communication—can someone test it?”
- “I want to try this remote I/O, but we don’t have the testing environment in-house…”
Feel free to reach out!If lending equipment or sharing your configuration is possible, we’re happy to verify it and share the results through articles and videos.
(We can keep company/product names anonymous if requested.)
How can you support us?
Currently, our activities are nearly all unpaid, but creating articles and videos takes time and a proper testing environment.If you’d like to support us in continuing and expanding this content, your kind help would mean a lot.

This time set to Manaul 0004 1.
Done!
Open EDS File via EZ
We want to know the Safety Class0 communication Instance number of Euchner’s MGB-L2B-EIA-R-136508, so we open the EDS File for MGB-L2B-EIA-R-136508 in the EZ-EDS tool.
Install EDS File
Click on EDS Library for CIP Safety to create an EDS File for Euchner’s MGB-L2B-EIA-R-136508.
Click New EDS File.
This is the EDS File creation screen in Sysmac Studio.
Vendor ID
The Vendor ID should match the Vendor ID value of Euchner’s MGB-L2B-EIA-R-136508 as indicated in EZ-EDS.
Vendor Name
The Vendor Name should match the Euchner MGB-L2B-EIA-R-136508 Vendor Name value displayed in EZ-EDS.
Product Type
Product Type should match the Euchner MGB-L2B-EIA-R-136508 Product Type value displayed in EZ-EDS.
Product Type String
The Product Type String should match the Euchner MGB-L2B-EIA-R-136508 Product Type String value displayed in EZ-EDS.
Product Code
The Product Code should match the Euchner MGB-L2B-EIA-R-136508 Product Code value displayed in EZ-EDS.
Product Name
The Product Name should match the Euchner MGB-L2B-EIA-R-136508 Product Name value displayed in EZ-EDS.
Major Revision
Major Revision should match the Euchner MGB-L2B-EIA-R-136508 Major Revision value displayed in EZ-EDS.
Minor Revision
Minor Revision should be set to 2. The door lock used in this article is Firmware 1.2.
Safety Input‐ Input Assembly Instance
To find the instance number of the Safety Input, open Connection Manager>Connection1 and click “Create Decode Path” under Path.
The connection Path of Connection1 is displayed here.
Change the display of the Instance number to a decimal number.
Match Safety input>input Assembly Instance to the Production IO Path value of 1025.
Safety Input‐ Output Assembly Instance
Set Safety Input>Output Assembly Instance to match the Producing I/O Path of 1279.

I/O Mapping
Next, we want to use the data exchanged by MGB-L2B-EIA-R-136508 and CIP Safety in the safety program, so we open the I/O Map.
You can add them one by one manually, but Sysmac Studio can automatically declare safety variables.
Select all the groups of variables you wish to automatically generate>right click>Click Create Device Variable with Profix.
Sets the Prefix of the variable auto-define.
Done!
Safety Program
To create a safety program this time, open Program0 in Programming>POUs>Programs>Default.

Program
Here is the safety program we have created.
Network1,2
Network1,2 creates a timer that turns on and off repeatedly for 1 second.
Network3,4,5
Network3, 4, and 5 retrieve the status of Euchner’s MGB-L2B-EIA-R-136508 main unit.
Network6,7,8,9
Network6,7,8,9 get button status for Euchner’s MGB-L2B-EIA-R-136508.
