Before You Begin... Gathering What You Need

Gather the following items before you begin using the flash upgrade . (Items marked with an aster isk (*) are inc luded 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

ATTENTION: You must install and run the PLC-5 flash tool on a computer boo ted up in DOS 6.22 or later.

Do not use a DOS window running und er W indows 95 or Windows NT.

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:

ATTENTION: Pay strict attention to the flash tool procedure. Failure to f ollow this procedure exactly may

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.

result in an inoperable processor.

Step 1 - Preparing the PLC-5 Processor

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.

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 of f 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.
