Safety Manual (AADvance Controller)

Configuring SNCP Safety Network

The SNCP protocol can be configured in the AADvance controller to provide

a safety network; refer to the AADvance Configuration Guide (Doc No.
553633) for detailed configuration procedures.

For SNCP bindings to be used in a Simplex Network configuration, SIL

3 can be achieved but the following conditions must be met:



For de-energize to trip configurations, associated SIF outputs shall be

configured to shutdown on loss of communications.



For energize to trip configurations link failures shall be repaired within the

MTTR.

Note: Additional measures must be considered for ensuring that the process
remains within its safe operating parameters during the repair time; these

additional measures must be defined in the Operating and Maintenance
procedures written for maintaining the SIF for the specific Plant or Process.
