About the Module
The ControlLogix 1756-RIO module connects a ControlLogix processor to a
remote I/O network.
The module can act as a scanner or as an adapter on the network. For additional
information, see publication
.
1756-RIO Module as a Scanner
As a scanner, with one remote I/O channel, the 1756-RIO module scans I/O on
a remote I/O network.
The module supports the following:
•
All remote I/O baud rates: 57.6, 115.2, 230.4 Kbaud
•
Rack numbers from 0…76 octal
•
All combinations of partial racks
•
Up to 32 physical adapters
To support 32 physical adapters, you must use an 82 resistor; 150
resistors allow only 16 adapters.
•
Block transfers at all possible locations
The module can update block transfers (BTs) automatically via the 1756-RIO
module or can be controlled by the ControlLogix controller. It transfers all I/O
via produced/consumed connections over the backplane to the controller.
IMPORTANT
This module is shipped in scanner mode, with a blank
configuration.
