■  Switchover in case of device or cable failure Only takes One Cycle

■  Redundant masters also supported

■  Failure of a device does not lead to complete networks shut down.

■  Drag chain Application

Robustness of RTOS- QNX

■ QNX is a TRUE Microkernel

■  Each Application, Device Driver, System Resources are built as an individual piece of software, completely independent from one another

■  MMU support providing full protection

■  Each individual piece of software has complete isolation and protection for all other pieces of software

■  If any software fails, the Microkernel and all other software will not be affected

■ Critical Process Monitor (HAM) monitors components and sends notification of  component failure

■  Guardian process provide software failover for HAM to insure the CPM can not be a single point of failure

■  Client side library allows you to easily design your system to reconnect instantly and transparently

■   CPM  provides heartbeat services to detect component hangs – this allows the system to monitor itself
