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. Since you removed the controller from the chassis, you must reenter the
computer’s Ethernet IP address and subnet mask (for example,
255.255.255.0 for Class C).The controller should have an IP address
with the same first three octets as the computer’s Ethernet network
interface address.
If it doesn’t, then you can assign the IP either by going online with the
controller over DH+ or serially, and configuring the IP address for
Channel 2 via the channel configuration screen (uncheck the BOOTP
enabled box). Or, by setting up a BOOTP server with this module’s
assigned IP address.

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. Disconnect all cables (serial, DH+, ControlNet, Ethernet, etc.) from
the controller.
3. Remove power from the controller and remove it from the chassis.
4. Remove the controller battery cover and disconnect the battery. This
resets the serial port to its default configuration so that the controller
and ControlFLASH can communicate.
5. If applicable, disconnect the coprocessor or Ethernet Interface sidecar
module.
6. Verify that the serial port DIP switches are set for RS-232.
7. Reinstall the controller and apply power.
8. Turn the controller keyswitch to PROGRAM mode.
ATTENTION
You must save the controller’s processor memory to
your hard disk or to an EEPROM. If you do not,
