Introduction
The CIP Safety target device is configured using a safety network configuration tool (SNCT). It is not configured using the Control Expert software. The SNCT is provided by the CIP Safety device vendor, and thus is device dependent.
Use the SNCT to:
Configure and download to the device the necessary settings for device operation.
Configure for the device, then copy and transfer to the Control Expert software, a device-specific Safety Configuration Identifier (SCID). The SCID is also referred to as the device Configuration Signature. It is used in Control Expert when configuring the Originator -> Target connection.
Assign to the device its unique TUNID, consisting of a:
Unique IP address.
NOTE: The SNN is usually generated by the Control Expert configuration software (as part of the Originator -> Target connection configuration) and applied to the device. The IP address is entered both in the SNCT and in device connection DTM in Control Expert.
Configuring the SCID
The SCID is set in the SNCT and serves as the unique hexadecimal configuration identifier for the CIP Safety target device. It is a concatenation of a:
Safety Configuration CRC (SCCRC): a cyclic redundancy check (CRC) value of the CIP Safety device configuration settings, consisting of 4 octets.
Safety Configuration Time Stamp (SCTS): a date and time hexadecimal timestamp value that consists of 6 octets.

|---|---|
RISK OF UNINTENDED EQUIPMENT OPERATION if you configure an M580 CPU as a CIP Safety originator,
test and verify the CIP Safety functional behavior of the system before
using CIP Safety communication to control the related safety function.
After testing and verification are successfully completed, enable
the CIP Safety target configuration signature (if one exists) in the
Control Expert CIP Safety DTMs. Failure to follow these instructions can result in equipment damage. | |
After creating the SCID using the SNCT, you can enter the elements of the SCID into the device DTM tab in Control Expert:
: Enter the SCCRC value.
: Enter the date the SCID was created (mm/dd/yyyy).
: Enter the time the SCID was created (hh/mm/ss/ms).
CIP Safety Device Configuration Sequence
The following sequence describes a typical CIP Safety device configuration process:
Obtain the device SNN (received from Control Expert).
Apply the SNN inside the vendor SNCT.
Perform a safety reset of the device (optional: if originator OUNID has changed since the last time the device has been connected).
Apply the TUNID into the device.
Determine the configuration settings that will control device behavior.
Configure the device with the vendor SNCT (safety network configuration tool).
Lock the configuration and verify the configuration accuracy.
Record and save the parameters to later use in the originator configuration (SCID, Assembly numbers, IP address, and so forth).
Save a copy of the device configuration for further use (for example, if the device needs to be replaced).
