1756-RIO Module
Requirements The requirements for the module to operate include the installation of:
 RSLogix 5000 programming software, version 17 or later, and the
associated controller firmware.
 RSLinx software, version 2.54 or later, with an activation. Use RSLinx
Gateway or RSLinx Professional software. Do not use RSLinx Lite
software.
 the 1756-RIO module add-on profile from the CD provided with the
module.
 the 1756-RIO module installed in a 1756-ControlLogix chassis.
The 1756-RIO Modes The 1756-RIO module can be used in various capacities depending on the
user’s needs. First, decide which mode you want the 1756-RIO module to use.
In most cases, the module is used in scanner mode to scan and control remote
I/O data on a network.
In adapter mode, the 1756-RIO module can perform two functions
simultaneously. First, the module can emulate one or more racks of I/O to a
scanner, exchanging data with that scanner (for example, a PLC-5, PLC-3, or
SLC). It can exchange data with the scanner as discrete data, or via block
transfers.
Second, the 1756-RIO module can act as a ‘shadow,’ referred to as Monitor
mode, to monitor racks on a remote network. The module listens to the
remote I/O and provides all inputs and outputs from the existing scanner to
the ControlLogix controller. Users can then run their converted logic against
those inputs, generate temporary outputs, and compare the existing outputs
with outputs generated by the new logic.
