AADvance Scalability
The AADvance design concept gives an expandable solution for each
application through its current range of I/O modules and termination
assemblies. Increased I/O capacity is possible because it is easy to add new
modules and it gives you the flexibility to create different architectures by
changing the I/O capacity and arrangement.
I/O Channel Capacity When creating a system, AADvance offers horizontal scalability. The
maximum I/O channel capacity of a single controller depends on if you
assemble I/O modules in simplex, dual or triple modular redundant
configurations.
You increase the I/O capacity of a controller by adding I/O base units,
termination assemblies and I/O modules. You can also use 16 channel
modules on a termination assembly and thus increase the I/O channel capacity
per module. An expansion cable allows you to use the controller second I/O
bus (I/O Bus 2) and add up to 24 I/O modules giving a total of 48 I/O
modules per controller.
An AADvance system also supports and integrates fully with existing
MODBUS subsystems and, through its own server, supplies interoperability
with HMIs and other OPC devices.
Simplex I/O Channel Capacity
When you need I/O modules arranged in simplex configurations you must use
the simplex termination assembly for each module type. You can use a physical
arrangement of 8-channel and 16-channel input modules with their simplex
termination assemblies, also any arrangement of output modules with simplex
termination assemblies. For example, you can put all digital inputs together in a
rack and all analogue inputs together, or mix them together.
The maximum number of simplex I/O channels is limited only by the selection
of modules. For example, 16 x 16 Channel input modules and 32 x 8 Channel
output modules, equals a maximum of 512 channels.
