Your computer must meet the following requirements to perform the
firmware update:
•at least a 486 processor
•Windows 95, Windows 98, or Windows NT, or later, operating system
•at least 16 Mbytes of available memory
To perform Ethernet Series C, or later, firmware updates, you will need a

Update Procedure in this
Document
ATTENTION
You must save the controller’s processor memory to your
hard disk or to an EEPROM. If you do not, the
controller’s user memory will be lost because the
firmware update procedure erases memory.

Important User Information
Solid state equipment has operational characteristics differing from those of
electromechanical equipment. Safety Guidelines for the Application, Installation and
Maintenance of Solid State Controls (Publication SGI-1.1 available from your local
Rockwell Automation sales office or online at http://www.ab.com/manuals/gi)
describes some important differences between solid state equipment and hard-wired
electromechanical devices. Because of this difference, and also because of the wide
variety of uses for solid state equipment, all persons responsible for applying this
equipment must satisfy themselves that each intended application of this equipment is
acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or
consequential damages resulting from the use or application of this equipment.
The examples and diagrams in this manual are included solely for illustrative purposes.
Because of the many variables and requirements associated with any particular
installation, Rockwell Automation, Inc. cannot assume responsibility or liability for
actual use based on the examples and diagrams.

ATTENTION Preventing Electrostatic Discharge
This equipment is sensitive to electrostatic discharge, which can
cause internal damage and affect normal operation. Follow these
guidelines when you handle this equipment:
•Touch a grounded object to discharge potential static.
•Wear an approved grounding wrist strap.
•Do not touch connectors or pins on component boards.
•Do not touch circuit components inside the equipment.
•If available, use a static-safe workstation.
•When not in use, store the equipment in appropriate
static-safe packaging.
ATTENTION This version of ControlFLASH is only suitable for this firmware
update. Do not use this version of ControlFLASH to update
firmware on any other PLC-5 programmable controller.

Programmable Controllers
- 1785-L20E
- 1785-L40E
- 1785-L80E
Series C and D
To update these series of Ethernet PLC-5 firmware, you must first use
ControlFLASH through the Ethernet channel, and then replace the applicable
EPROMS. To start this firmware update, follow these steps:
Step 1 - Prepare the PLC-5 Programmable Controller
1. Save the controller’s processor memory to your hard disk or to an
EEPROM.
2. Remove power from the controller.
3. Remove the controller battery cover and disconnect the battery.
4. Remove the controller from the chassis.
WARNING When you connect or disconnect the battery, an electrical arc can
occur. This could cause an explosion in hazardous location
installations. Be sure that power is removed or the area is
nonhazardous before proceeding.
• For safety information on the handling of lithium batteries,
including handling and disposal of leaking batteries, refer to
Guidelines for Handling Lithium Batteries, publication AG-5.4
• Store batteries in a cool, dry environment. We recommend 25°
C with 40% or 60% relative humidity. You may store batteries
up to 30 days between -45° - 85° C, such as during
transportation. To avoid possible leakage, do not store batteries
above 60° C for more than 30 days.
WARNING When you install or remove the module with power applied, or
you connect or disconnect the serial cable with power applied to
this programmable controller or the device on the other end of
the cable, an electrical arc can occur. This could cause an
explosion in hazardous location installations. Be sure that power is
removed or the area is nonhazardous before proceeding.
ATTENTION
You must save the controller’s processor memory to your
hard disk or to an EEPROM. If you do not, the
controller’s user memory will be lost because the
firmware update procedure erases memory.

5. Locate and document the controller’s hardware Ethernet address.
The address is on the circuit board label toward the back of the
controller.
6. If applicable, disconnect the coprocessor or Ethernet Interface sidecar
module.
7. Reinstall the controller into the chassis.
8. Apply power to the controller.
9. Through the Ethernet port, use either a switch, hub or crossover cable
to connect the computer to the controller. Make sure the TCP/IP is
configured and running on the personal computer.
10. Assign the controller’s IP address by going online with the controller via
DH+ or serially. Use the channel configuration screen to configure the
IP address for Channel 2 (uncheck the BOOTP enabled box).
11. Turn the controller keyswitch to PROGRAM mode.

Step 2 - Install the ControlFLASH Software
1. Insert the ControlFLASH disk into the floppy drive of your computer.
2. Browse the A: drive and select the setup.exe program.
3. If you have an earlier version of ControlFLASH installed, we
recommend to install this version into the same directory.
4. Follow the Setup Wizard as it guides you through the installation
process.
Step 3 - Perform the ControlFLASH Update
1. If you have not already done so, connect the computer to the controller
through the Ethernet channel:
–use either a switch, hub or crossover cable to connect the computer
to the controller
2. Close all applications including RSLinx.
ATTENTION
Failure to follow these procedures exactly or to
cause an interruption during them may result in
an inoperable controller.

4. Remove power from the controller.
5. Remove the controller from the chassis.
3F - Start the firmware update.
Click Yes.
The progress indicator shows how much of the
update has been performed.
Important: This update can take up to two minutes
to complete.
3H - Follow the power cycle instructions during and after the update process.
When the update is complete, the software will prompt
you to cycle power.
Important: Do not click OK until you complete the next
three steps:
- “Install the New Firmware EPROMS”
- “Apply the Firmware Revision Label”
- “Complete the Firmware Update”
These procedures are detailed on the following pages.
3G - Check the STAT LED on the PLC-5. If it is flashing green, the ControlFLASH update was
successful - continue to step 3H. If the STAT LED is not flashing green, the update was not
successful - call Rockwell Automation Technical Support at 440-646-3223.
