FW3sb56r
Updating Logix5000 Firmware
After completing this lesson, you should be able to update module
firmware.
When You Will Do This
You will perform these tasks in the following situations:
 You will need to update module firmware:
-- When installing a brand new ControlLogix controller
-- When upgrading to a newer version of RSLogix 5000
software to ensure hardware and software remain in lockstep
Review
Activity: Your instructor will briefly review uploading,
downloading, and going online to a controller.
Updating Module Firmware
To use all of the features of a new revision of RSLogix 5000
software, controller and servo module firmware must be in lock-step
with software.
The firmware loaded in Logix5000 controllers and
motion modules must match the version of
RSLogix 5000 software you are using.
There are three methods available for updating module firmware:
Method How Used Devices Supported Communication Supported
ControlFLASH Utility
Standalone tool (can be
launched manually or through
RSLogix 5000 software). Controllers, communication
modules, I/O modules,
SERCOS drives, and other
devices.
Valid CIP path to device being
updated (includes serial,
DeviceNet, ControlNet,
EtherNet/IP).AutoFlash Function
Integrated with RSLogix 5000
software. It automatically
checks firmware during project
download.
(Continued)
Note that this lesson briefly reviews
prerequisite concepts before presenting
the firmware piece. Tailor this lesson as
needed.
What You Will Learn
Before You Begin
The PowerPoint presentation
contains hidden slides that can
be used to conduct the review.
Topics include keyswitch positions;
uploading, downloading, and going
online; and interpreting a
communications path.
State that customers can obtain the
required revision levels at the
support.rockwellautomation.com/support
website for ControlFLASH.
Note that a minimum of one
communications device is required
to update modules. Serial
communications can be
used, but data transfers
at the slowest rate.

1--2 Updating Logix5000 Firmware
E 2012 Rockwell Automation, Inc. All rights reserved. Rev. August 2012
FW3sb56r
Method How Used Devices Supported Communication Supported
Firmware Supervisor
Integrated on the controller
CompactFlash card and runs
without user intervention.
Supports local and remote
devices that:
 Are in the I/O tree and
configured as Exact Match.
 Support firmware upgrades
via ControlFLASH.
 Are at a hardware revision
that supports the firmware
stored for that device.
Supports all communication
paths to devices in the
controller I/O tree that also
support ControlFLASH.
When updating a module’s firmware, note the
following key points:
 Updating a module will delete the current
module contents.
 Updating module firmware temporarily disables
the module from controlling other devices.
Evaluate what portion(s) of a process the
module may control before starting an update.
 Interrupting an update by disabling
communications or removing the module from
the chassis may damage the module.
Do not backflash a 1756-I/O module’s
firmware from firmware revision 3.x to 2.x.
Attempting to backflash or downgrade the
module’s firmware will irreversibly damage the
module. You must return modules damaged by an
attempt to backflash to firmware 2.x to Rockwell
Automation.
Do not flash a 1756-I/O module’s firmware
from firmware revision 2.x to 3.x. Attempting to
flash a module’s firmware will irreversibly
damage the module.
Do not backflash 1756-SOE (Sequence of
Events) modules at firmware revision 1.6 to
revision 1.5 or earlier. Backflashing SOE
modules at firmware revision 1.6 may cause the
SOE module to stop working and require that the
module be returned for repair.

1--3Updating Logix5000 Firmware
FW3sb56r
If you have questions regarding the compatibility of RSLogix 5000
software with specific controllers or hardware modules, contact your
local distributor or Rockwell Automation Technical Support.
To update module firmware.
Activity: As your instructor demonstrates these procedures, follow
along in the associated job aid(s).
- Download the first project and go online.
- Download the second project to the controller.
- What happens when the project is downloaded?
- How is this situation resolved?
- What tools are available for flashing module firmware?
Pay attention to these critical aspects of the demonstration:
"Tip
Here’s How
IMPORTANT: When performing
Exercise A, be sure to run the
Quick Start video for the
students on the overhead. This
will eliminate the need for
earphones or the distraction of
overlapping audio during the exercise.
IMPORTANT: To meet IACET CEU
requirements and fully prepare
certificate students for the final exam,
you must demonstrate all lesson
objectives using the proper job aids.
Use the steps below and the information
on the Demonstration Checklist to help
guide you during the demonstration:
IMPORTANT: Before performing this
demonstration, ensure that the controller
in slot 3 of your demonstration
workstation has been back-flashed to
a firmware version below version 17.
Use the FW3_1756R_DEM1.acd file to
download and go online to the controller
in Slot 1.
Use the FW3_1756R_DEM2.acd file to
download to the controller in slot 3.
When the firmware revision mismatch
occurs, show students how the
automatic firmware update feature
works.
Important: Emphasize that flashing
firmware will not be practiced in the lab.

Lesson 2
TS2sb56r
Creating and Organizing a New
RSLogix 5000 Project
After completing this lesson, you should be able to:
 Create a new RSLogix 5000 project file
 Modify controller properties
 Create a program and routine
 Adjust a program schedule
 Copy and reuse programs and routines
 Delete a routine, program, and task
 Verify tasks, programs, and routines
When You Will Do This
Before you enter the logic for your application, you have to
configure the tasks, programs, and routines that will run the logic.
Key Terms
Project/Project File: The RSLogix 5000 software file used to store
all programming and configuration information for a Logix5000
controller.
Project Organization
A Logix5000 controller is a preemptive, multitasking controller with
the following characteristics:
 Is single-threaded in that only one task will be active at a time
 Has the ability to interrupt an executing task, switch to a different
task, then return control back to the original task when the
interrupting task is complete
What You Will Learn
Important: This lesson covers the
default project organization. Periodic
tasks and event tasks are covered in
separate lessons.
Stress that deleting project components
is not as simple as selecting delete from
a right-click menu. Because deleting can
be done online, it is a more detailed
procedure.
Note that the use of tasks and programs
is a major difference from RSLogix 5 and
500 softwares.
Before You Begin
Note that .l5k text files are part of a
separate lesson.
State that the multitasking system is like
32 separate PLC-5 controllers that take
turns controlling.
Note that task execution is based on
priorities that are assigned by the user.
This will be discussed in detail later.

2--2 Creating and Organizing a New RSLogix 5000 Project
TS2sb56r
To maximize these multitasking capabilities, the following
containers are available to organize an RSLogix 5000 project:
 Task: A scheduling mechanism for executing its scheduled
programs.
 Program: A set of related routines and tags.
 Routine: A set or sequence of executable code.
Default Project Structure
By default, there is one task, program, and routine created in each
new project:
Default Structure
and Names
The names and properties of these components can be modified to
suit your application.
Creating a New Task
A task triggers the execution of its scheduled programs. The
following table outlines the type of tasks that are available:
Task Type Usage Icon
Continuous
A task that runs continuously but can be interrupted by
periodic or event tasks (default task type).
Periodic
A task that executes regularly at a user-specified rate.
When called, it will interrupt any lower priority tasks.
Event
A task that is triggered only when a specific event
occurs. When called, it will interrupt any lower priority
tasks.
Clarify that tasks and programs are
organizing elements (like folders in
Windows Explorer). Routines contain the
actual ladder logic.
When reviewing this graphic, note the
following elements:
1. Each task can be divided into
programs based on function, area,
or some other attribute.
2. Each program can have as many
routines as memory allows. One
routine must be defined as the main
routine and the rest will be
subroutines.
"Tip
If students are familiar with PLC-5
controllers, relate the periodic task to an
STI.
Important: Remind students that
periodic and event tasks are only
mentioned here as an overview. This
topic is presented in more detail in a
later lesson.

2--3Creating and Organizing a New RSLogix 5000 Project
TS2sb56r
Reference: Logix5000 Controllers Design Considerations,
1756--RM094
1. Find the Logix5000 Controller Comparison tables at the front of
the manual.
2. Compare the number of tasks you can have in various controllers.
Continuous Task
A continuous task has the following characteristics:
 Is a background task that executes any time other operations, such
as periodic or event tasks, are not executing
 Operates in a self-triggered mode (automatically restarts after
each completion)
 Can be interrupted by a periodic or event task
 By default, has the lowest priority (one lower than the lowest
periodic or event task)
 Only ONE task can be continuous
Watchdog Timers
A watchdog timer monitors the execution of a task. The timer is
started when a task is initiated and stops when all programs within
the task have executed.
A watchdog timer continues to run even if a task is interrupted, so
it’s important that the watchdog timer is set to a large enough value.
Ensure that the time period is longer than the sum
of the execution time of all the programs assigned
to the task. If the controller detects that a periodic
task trigger occurs for a task that is already
operating, a minor fault occurs.
If a watchdog timer reaches its configured preset, a
major fault occurs. Depending on the controller
fault handler, the controller may shut down.
?If a ControlLogix controller has one
continuous task and 4 periodic, how
many event tasks could it have?
Answer: 27 (27+4+1=32)
?If a DriveLogix controller has zero
continuous tasks and 4 periodic, how
many event tasks could it have?
Answer: 4 (4+4 = 8)
Compare this to the program files in an
RSLogix 5 or 500 project.
Note that “self-triggered” means that as
soon as it ends, the task begins again. It
also means that the routine does not
have to be called (activated).
If students are familiar with Basic
programming, compare this to
programming a Goto 10 statement in the
last line.
Note that the watchdog timer in a PLC-5
processor is for the entire controller.
Here, the watchdog timer is set for each
task.
"Tip
Point out that the last scan and max
scan can be viewed online. In a different
lesson, students will learn to monitor the
scan times using ladder logic
instructions.

2--4 Creating and Organizing a New RSLogix 5000 Project
TS2sb56r
Inhibited Task
The following icon in the Controller Organizer indicates that the task
has been prevented from executing by a user option or instruction:
Inhibited Task
This inhibit option can be used to test, diagnose, or start up a project.
If a task is inhibited, the controller still pre-scans
the task when the controller transitions from
Program to Run or Test mode.
Creating a Program
A program is the second level of scheduling within a project. A
program has the following characteristics:
 Each task can schedule up to 100 programs.
 When a task is triggered, its programs execute in sequence from
the first scheduled to the last scheduled.
Programs within a task can access input and output data directly
from controller-scoped memory:
 Code within any program can modify controller-scoped data.
 Code within a program can also modify program-scoped data:
-- Code within one program cannot access or modify the data
that is local to a different program.
The Create New Program button is shown in the following graphic:
Create New Program
Optional Toolbar
To inhibit a task:
1. Inhibit all tasks except one.
2. Run the project and monitor the
execution of the active task.
3. When the task meets the
requirements of the system, repeat
the process, testing a different task.
"Tip
State that tasks can also be inhibited or
uninhibited using SSV instructions.
Mention that for information on
equipment phases, attend the
PhaseManager course.

2--5Creating and Organizing a New RSLogix 5000 Project
TS2sb56r
Adjusting a Program Schedule
Programs can be scheduled in a specific task or left unscheduled:
 Original equipment manufacturers may create one project and
then schedule or unschedule a program depending on the
equipment’s required functionality.
 Maintenance or field service technicians may create
troubleshooting programs that are left unscheduled until needed
to test a project.
The following example shows a program schedule:
Unscheduled
Programs
Program
Schedule
Adjust Order
Actual Program Scan Time
The software can display the maximum scan time and the last scan
time in microseconds for a selected program:
 Scan time is based on the number and type of instructions.
 These values are execution times for the program and do not
include any time spent waiting for other programs or tasks.
 These values are for display only.
Values can also be monitored using specific instructions in code.
Mention that the entire schedule can be
viewed in the Task Properties dialog
box. Otherwise, programs can be quickly
scheduled or unscheduled in the
Controller Organizer.
Note that these methods will be
demonstrated in the Here’s How section.
Add that unscheduled programs do not
use any scan time.
State that a Compute instruction will
take longer than using simple multiply
and divide instructions.
Note that the GSV instructions that are
used to monitor program time are
presented in a different lesson. "Tip
