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.

For A-B Internal Use Only Publication 1785-6.2 March 1998

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.

3. Select the appropriate script file by moving the cursor to the file name and

pressing . Script files are named as follows:

Lwwx_yz.ini

4. On your computer, select the communication port (COM1 or COM2) by

moving the cursor to select the port and pressing .

5. Make sure you have established a connection. This could take about

60 seconds.

• 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:

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.

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:

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
