The 1771-SDN/C PLC-5 DeviceNet scanner module acts as an
interface between DeviceNet devices and the PLC-5
programmable controller. The scanner module communicates
with DeviceNet devices using the latest DeviceNet Master
Library (DML) to:
•
read inputs from a device
•
write outputs to a device
•
download configuration data
•
monitor a device’s operation status
Communicating in the form of block transfers and discrete I/O,
the scanner module exchanges device I/O data, status
information and configuration data. The scanner has two
channels that let you connect to two DeviceNet networks.
The 1771-SDN/C scanner module is a direct replacement for
the series B version - but has new features and benefits. The
series C module has a series B-compatible switch setting to
allow for direct replacement of a series B module without
requiring any changes to the existing system.

PLC-5 Controller Choices
Protected PLC-5 controllers
•
guard individual data elements
•
protect specific elements within the
processor status file
•
reduce the risk of unauthorized
program modifications
•
plus the features of the Enhanced
PLC-5 controllers
The protected PLC-5 controller lets you limit access to critical or
proprietary areas of programs, selectively guard controller memory
and I/O, or restrict use of controller operations. The distinctive
safety-yellow labels on the controller identify the protected
PLC-5 controller.
Use the programming software to assign class privileges to specific
user accounts or a user’s job function, such as system administrator,
plant engineer, maintenance engineer, or operator. Using four
privilege classes and associated passwords, you can limit access to
critical areas of programs and restrict access to:
• communication channels
• remote nodes attached to the ControlNet or DH+ network
• program files
• data files
The protected PLC-5 controller expands system validity and security
beyond that provided by the password-and-privilege feature of the
other PLC-5 controllers. The Rockwell Automation clutch/brake
application package combines the protected PLC-5 controller with
specially-designed software to support stamping press applications.

Programming Software Choices
The PLC-5 controllers support multiple industry-standard
programming languages. You can program in structured text,
function block, sequential function charts, or ladder logic.
This versatility means you can maintain and troubleshoot programs
in the same language that you develop them.
The RSLogix5 family of programming software products offers a
common means of viewing PLC-5 programs. For current 32-bit-based
WindowsTM products:
RSLogix offers:
Which means you can:
free-form editing
concentrate on your application logic rather than
keeping syntax correct as you write the program
drag-and-drop editing
cut, copy, and paste data table elements, rungs,
SFC components, or whole program files
point-and-click I/O configuration
assign a module in your configuration with a
simple click or drag-and-drop
Programming Software Choices
31
RSLogix5 increases your productivity by:
•
including structured text and sequential function chart editors that
are based on IEC 1131-3 requirements
•
letting you create libraries of reusable programming
•
supporting symbolic ladder and structured text programming so
that you can use symbols you create
•
exporting to or importing from spreadsheet programs using the
comma-separated-value format
•
providing advanced diagnostics through a customer data monitor
that lets you view the status of bits, timers, counters, and other
data elements
Software Choices
Rockwell Automation also offers A.I. series programming software
to support DOS and non-32-bit Windows environments. Your
investment in these programming packages can be re-used in
RSLogix5.

Applying Backup Solutions
ControlNet backup module
Increasing system fault tolerance
The ControlNet backup module provides backup of ControlNet I/O.
A secondary controller qualifies critical control information with the
primary controller. Both controllers consume information from
inputs and connect to outputs, but only the primary controller controls
the outputs. The secondary controller establishes control of outputs if
the primary controller shuts down.

The ControlNet backup module provides:
Benefit:
high performance, deterministic delivery of I/O data
The backup module supports standard features of ControlNet: high-speed data
transmission (5Mbps), user-selectable, deterministic delivery of remote I/O data.
execution of control programs in both the primary
and secondary controller
Both the primary and the secondary controller view remote inputs and continuously execute
their control program. Switchover time is faster because there is no need to crossload data
table information or control programs.
two selectable modes of backup operation
Select:
• synchronous for a system where both controllers must keep as close as possible to
each other to minimize data table divergence.
• asynchronous for a system where application performance, such as program scan
times, must be optimized.
redundant cabling
You have the option of wiring a second, or redundant, cable to all remote I/O nodes. Should
one cable break, the second cable will provide continued and uninterrupted transmission.
