About UniStream® Remote I/O
This line of remote Ethernet I/O is compatible with UniStream controllers. The line comprises an Ethernet-
based Remote I/O adapter and I/O Remote modules.
You configure Remote I/Os in UniLogic, using the Hardware Configuration editor, and connect them to the
controller via Ethernet cable
A single UniStream Remote I/O adapter can support up to 63 12mm wide I/O modules. Each adapter
comprises two Ethernet ports; this enables users to link an adapter to a controller, and then daisy-chain
adapters to support up to 8 adapters per controller, increasing the total number of I/Os supported by a single
UniStream.
UniStream Remote I/O offer a broad range of modules; each module offers a different configuration of
analog and digital outputs.
Note that the exact number of I/Os that can be included per adapter is dependent on the specific I/O
connected to that specific adapter.
The adapter is limited to process 192 data bytes for inputs and 192 data bytes for outputs.
Each digital input/output point process data is 1 bit (minimum 1 byte per module if module data size is less
than 8 points) while each analog input/output is 2 bytes (8 inputs/outputs module will be 16 bytes of process
data).

UniStream Remote I/O and Uni-I/O modules

You may use both lines in the same application at the same time.
Since the two lines communicate via different protocols and physical connections:

They work independently of each other

You can use both lines with the same controller at the same time.
Note that the adapters and modules of each line are not interchangeable.
You may only use:

Uni-Local Expansion Adapters with Uni-I/O modules

UniStream Remote I/O Adapters with UniStream Remote I/O modules.
