In this Tutorial I will show you how to configure a CIP Safety Network – Omron NX-CSG320+SL5500 as a Safety Originator and Molex CIP Safety Hash IO Module TCDEC-8D4B-DYU-GW as Safety Target step by step, then create some simple safety logic in the Omron CPU.And some basic concepts and keywords in Omron CPU and CIP Safety are also introduced.
Let’s Start!

please follow this link to download the Omron Engineering tools Sysmac Stuto.
Keyword
Omron CPU
RUN Mode
A mode that indicates the CPU is running the validated Safety Application, Saved in the non-volatile memory. The BOOL Variables can not be controlled, and forced refreshing,present value modifications are not allowed.
PROGRAM Mode
A mode that indicates the Safety Program inside the CPU is stopped, The BOOL Variables can not be controlled, and forced refreshing,present value modifications are not allowed.
DEBUG Mode
A mode that indicates that for the programmer to debug the unvalidated safety programs.
This mode can only be operated when the Sysmac Studio is online with a CPU Unit.
we can check the safety program in this mode.
And the Safety Program will be automatically Transferred to the main memory of the Safety CPU.
Safety Validation
It is a process to append the information to the safety program, if required. The validated safety program will auto transfer to the non-volatile memory of the Safety CPU.
CIP /CIP Safety
TUNID
TUNID=Target Unique Network Identifier,It is an ID to identify the Safety Target in the Safety Forward Open Request.
- A General status=0x01, extended status 0x80D is returned from Target for the Safety Forward Request, if the TUNID is not set in the Target.
- A General status=0x01, extended status 0x80E is returned from Target for the Safety Forward Request, if the TUNID is not matched.
In Profisafe, A F-Address is needed and In FSoE, A safety address also needs to be configured, Right?
Safety Reset
Safety Reset is an operation with Safety Supervisor Object Specific Services 54hex,that reset the parameter,TUNID,etc..Once you set the TUNID, you need to operate the safety reset to re-configure the TUNID.
SNCT
SNCT=Safety Network Configuration Tool,A tool to configure the CIP Safety
network and provide the safety series like Set TUNID,Safety Reset.
EDS File
A EDS File is just like GSDML file in profinet, ESI in ethercat ,devices configuration files that are imported into Engineering tools.
Configuration
As I mention in the beginning of the tutorial, this is the configuration.
Implementation-1
In this Implementation, I will show you how to configure the CIP Safety network step by step.
