Controller architecture
Specify a suitable redundant Allen-Bradley control architecture where continuity of process control requires it.
Redundancy & availabilityDesign for the interruption
Design for the interruption
you need to avoid.
Control, network, power and cooling redundancy solve different problems. Build the availability plan around your process and its actual failure risks.
Define what must keep running.
Availability is a coordinated architecture, not a single redundant component. We agree the required response to each interruption before selecting the equipment.
Network continuity
Review supported network topologies, device compatibility and recovery requirements across controllers, I/O and drives.
Control-power resilience
Define power sources, redundancy modules and any UPS scope around the loads and required ride-through behavior.
Include the environment in the plan.
Cooling capacity, equipment service access and control-power maintenance affect how the complete system operates during an outage or repair.
Cooling strategy
Select lead/lag or redundant HVAC with the actual equipment heat and ambient conditions established. Redundancy capacity is confirmed for the specific project.
Defined acceptance
Agree the failure scenarios to demonstrate, expected response, alarms and conditions that require a controlled shutdown.
Engineer the right level of resilience.
Tell us the cost of an interruption, which loads must remain available and how long the system needs to continue. We can then distinguish necessary redundancy from complexity that brings little operational value.
