9-4 PC Performance for ProcessLogix Systems

Rockwell Automation works with Dell to build PCs to specifications to
meet the needs of Process Control Systems. Although based on
systems available to the General Public, these systems will typically
include such items as Error Correcting Memory, internal hardware
sensors, management applications, and other features that differentiate
them from the typical household or business PC. Once built, these
systems are then brought in for evaluation and testing.

Rockwell Automation then tests these platforms to verify that they
meet certain standards. This is necessary to verify that the PC will
work in many types of Process Control scenarios.

Qualification continues with the Operating System installation. How
the system performs is very dependent on the OS software
configuration, which includes the device drivers that interact with the
hardware. Many performance characteristics are derived from this
interaction, while also working towards optimizing the user
experience.

Redundant Networking

A configuration option, it protects the system from network faults. The
system monitors the network status and will automatically fail over
when the system detects a fault.

Server Redundancy

This allows the system to continue operating even when a PC fails
which was hosting the ProcessLogix® Server. All systems in the
configuration will shift to the backup system if the primary node has
failed.

Fast Failover

Some processes need to be more tolerant to total system failure. This
option includes more stringent monitoring of the two servers and a
faster switch-over time.
