Solutions Handbook (AADvance Controller)
The significant benefits of the AADvance controller are its performance and flexibility.
Being designed to IEC 61508 it meets both SIL2 and SIL3 application requirements
from the basic range of modules and mixed SIL rated applications can be covered by
this range of modules.
All of the configurations are readily achieved by combining modules and assemblies
without using special cables or interface units. System architectures are user
configurable and can be changed without major system modifications. Processor and
I/O redundancy is configurable so you can choose between fail safe and fault tolerant
solutions. This scalability is user configurable, therefore, there is no change to the
complexity of operations or programming if you choose to add redundant capacity to
create a fault tolerant solution.
A controller is built from a range of compact plug-in modules that are straightforward
to assemble into a system. They can be mounted onto DIN rails in a cabinet (see
photograph) or directly mounted onto a wall in a control room. They do not require
forced air cooling or special environmental control equipment. However, certain
consideration to the cabinet type must be applied when used in hazardous
environments.
A secure network communications protocol, developed by Rockwell Automation for
the AADvance system, permits distributed control using new or existing network
infrastructure while ensuring the security and integrity of the data. Individual sensors
and actuators can connect to a local controller, minimizing the lengths of dedicated
field cabling. There is no need for a large central equipment room; rather, the
complete distributed system can be administered from one or more PC workstations
placed at convenient locations.
