Safety Manual (AADvance Controller)
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.
