The AADvance design concept provides an expandable solution for every application
through its current range of I/O modules and termination assemblies. Increased I/O
capacity is possible because of the ease and simplicity for adding new modules and the
flexibility for creating different architectures.
This chapter describes how you can expand the I/O capacity of a controller.

I/O Channel Capacity
The maximum I/O channel capacity of a controller depends on whether you arrange
I/O modules in simplex, dual or triple modular redundant configurations. The total
capacity of an AADvance system remains unlimited, because there are no restrictions
on the number of distributed controllers you can integrate through a network.
By adding new termination assemblies and I/O modules that simply plug together you
can increase the I/O capacity of a controller. You can also use 16 channel modules on
any existing termination assembly and thus increase the I/O channel capacity per
module from 8 channels to 16 channels. The T9310 expansion cable allows you to use
IO Bus 2 and increase the controller capacity by 24 I/O modules giving a total of 48
I/O modules per controller.
An AADvance system offers horizontal scalability with no technical constraints on the
number of distributed controllers within a single system. The system supports and
integrates fully with existing Modbus subsystems and, through its own server, provides
interoperability with HMIs and other OPC devices.
