Before You Begin... Gathering What You Need
Gather the following items before you begin using the flash upgrade.
(Items marked with an asterisk (*) are included in the flash tool
package you ordered.)
• flash firmware upgrade tool disk*
• PLC-5 processor whose firmware you want to update
(with chassis and power supply)
• personal computer with PLC-5 programming software installed
• shielded serial cable (1784-CP10 or 1784-CP11)
• this manual*
• firmware revision label*
• plug PROM(s) (if you require a plug PROM firmware update)*
Running the Software
You will copy the flash files to your hard drive.
Using the Flash Tool To successfully use the flash tool, you need to complete seven steps:
1. Prepare the PLC-5 processor.
2. Install the flash tool.
3. Perform the firmware upgrade.
4. Apply the firmware revision label.
5. Update the communication plug firmware, if necessary.
6. Reconnect the PLC-5 processor.
7. Uninstall the flash tool.
!ATTENTION: You must install and run the PLC-5
flashtoolonacomputerbootedupinDOS6.22orlater.
Do not usea DOS window running under Windows
95 or Windows NT.
!ATTENTION: Pay strict attention to the flash tool
procedure. Failuretofollowthisprocedureexactlymay
result in an inoperable processor.

Step 1 - Preparing the PLC-5 Processor
1. Save processor memory to your hard disk or to an EEPROM using your
PLC-5 programming software.
2. Remove the processor battery cover and disconnect the battery. This resets
the serial port to its default configuration so that the PLC-5 processor and the
flash tool can communicate.
3. Turn off processor power.
4. Disconnect all cables (serial, DH+, ControlNet, Ethernet, etc.) from
the processor.
5. Disconnect the coprocessor or PLC-5 Ethernet Interface module, if one
is connected.
6. Turn the processor keyswitch to Program mode.
7. Turn on processor power.
8. Attach the shielded serial cable (1784-CP10 or 1784-CP11) between
channel 0 on the PLC-5 processor and the serial port on the computer.
!
ATTENTION: You must save the processor memory
to your hard disk or to an EEPROM. If you do not, the
PLC-5 user memory will be lost because the flash
procedure erases processor memory.

Step 2 - Installing the Flash Tool
1. Boot the computer in DOS 6.22 or later. Do not use a DOS
window running under Windows 95 or Windows NT. Verify
that there is a DOS prompt on the screen.
2. Create the following directory on the programming terminal’s
hard drive by typing:
md c:\flash
3. Place the flash firmware upgrade tool diskette in the a: drive of
the programming terminal. Copy the files from this diskette to
the programming terminal hard drive by typing:
copy a:\*.* c:\flash
4. On the programming terminal, change to the following directory
containing the firmware files by typing:
cd c:\flash
Step 3 - Performing the Flash Upgrade
Follow these steps to upgrade the processor firmware.
1. Enter this command:
flash5
The flash upgrade catalog number selection screen appears.
2. Use the arrow keys to move the cursor to the catalog number of
the flash upgrade you want to download to the processor and
press .
!ATTENTION: Make sure you install this application
on the hard drive. Do not attempt to run it from the
floppy disk; it will not work.
!ATTENTION: Do not interrupt the flash download
process by disturbing the processor or computer.
Failure to do so may result in an inoperable processor.

If you received an error:
When the flash download begins:
• the processor’s COMM LED blinks green
• the processor’s PROC LED blinks red/green
• a percent complete status (0 - 100) appears in the middle
of the screen that indicates how much of the flash update
is complete
6. Wait for the flash update to complete. The upgrade should take
about 5 minutes to complete.
When the download is complete the status bar will be at 100%
and the screen will display this message: Processors Flash
Update Completed. Press Any Key to Continue.
If you received this error: Do this:
Processor not connected. a. Make sure the keyswitch is in Program
mode.
b. Make sure the processor power is on.
c. Check the serial cable.
d. Verify the COM port being used bythe
computer.

7. When the flash update is complete, cycle power to the processor.
8. Disconnect the serial cable that you used to perform the flash upgrade.
Step 4 - Applying the Firmware Revision Label
Important: It is important to apply this label to your processor to ensure you
receive the correct version back if you send it in for repair.
1. Turn off power to the processor.
2. Remove the processor from the chassis.
3. Apply the new firmware revision label in the space indicated by dotted lines
on the product identification label. The following figure shows where to
place the label on a series E PLC-5 processors and on older PLC-5 processors.
If the processor powers up with the: Do this:

Step 5 - Updating the Communication Plug Firmware
If you received communication plug PROM(s) with your order, you
need to update your PROM(s) to complete the flash upgrade.
1. Make sure you have already removed the battery cover and
disconnected the battery and disconnected any cables attached to
the processor.
!ATTENTION: Printed circuit board components can
be damaged during routine handling and installation.
Follow these precautions to reduce static electricity
discharges before you upgrade the processor firmware.
• Handle the printed circuit board by the case or
carrier without touching the pins or the edge
connector.
• Use a static-free workstation.
• Connect the static-free workstation to ground
through a minimum 200K ohm resistance.
• Wear a grounded, conductive wrist strap with a
minimum 200K ohm resistance.
• Ground all tools before you begin to upgrade the
firmware.
• Control the relative humidity of the installation
area. Ideal conditions are 40-60% relative
humidity.

2. Do one of the following:
3. Remove the PROM, observing the orientation of the PROM notch. Replace
the plug PROM, checking to see that the PROM notch is correctly oriented.
4. Reassemble and power up the processor.
Step 6 - Reconnecting the PLC-5 Processor
1. Reconnect the battery, any cables, and coprocessor or PLC-5 Ethernet
Interface module.
2. Reload your program and make certain that it runs properly.
(If you have any questions, call technical support at 440-646-6800.)
If you have a: Do this:

plastic cover.
b. Remove the cover.
c. Remove the two large screws and washers located in the
middle of the exposed circuit board.
d. Separate the two processor boards by pulling the
exposed circuit board at the backplane edge connector
away from the metal cover as you would open a book.

Step 7 - Uninstalling the Flash Tool
We recommend that you remove the flash tool directory and all of the files it
contains. Follow these steps to uninstall the flash tool.
Important: Make sure you are in the flash directory that you created on the
hard drive so that you do not accidentally delete the wrong files.
1. On the programming terminal, change to the directory containing the
firmware files by typing:
c:
cd \flash
2. Delete all files within that directory by typing:
del *.*
3. Change to the root directory by typing:
cd\
4. Remove the flash directory by typing:
rd flash
