**Subject: Seeking Assistance with Micrologix 1100 Firmware Update Issues** Hello Everyone, I recently attempted to update my Micrologix 1100 PLC to the latest firmware version 16. My unit is a 1763-L16BWA (Series A, Rev A, FRN 1). I utilized ControlFlash 15.01.00 on my Windows 10 PC, connecting through a Serial Cable with a USB/RS232 Adapter. Before starting the firmware update, I was able to connect to the PLC using RSLogix Micro and access the previous owner's program without any issues. However, during the update process, the installation gets stuck at block 25, the PLC reboots, and three LEDs below the power button start flashing. I'm concerned that I may have inadvertently bricked the device. Is there a way to recover from this situation? I greatly appreciate any advice or suggestions. Here are some relevant log entries for your reference: ``` Fri Apr 20 21:17:50 2018 [-------] User must install FactoryTalk AssetCentre Client 2.31 or above if attempting to log message to FactoryTalk AssetCentre Server.

I’m looking forward to any insights you might have regarding troubleshooting this firmware update issue or restoring functionality to my Micrologix 1100. Best, [Your Name]
I noticed the prices of frn 15.00 and 15.02 listed on the AB website. However, I couldn't find the price for 15.01. It's important to mention that all the other listings are for Series B controllers, while yours is from Series A.
Hello Mdim, I’m a bit uncertain about the details, but I did a search specifically for the year 1763 and found versions ranging from 10 to 16. I've noticed that there doesn't appear to be any distinct software variations between the A and B series. I successfully flashed the device using version 10, which included ControlFlash 8.01.001. Additionally, I adjusted the baud rate in the device manager for the COM port to align with the settings recommended by the older version of ControlFlash. Now, I plan to attempt flashing the device with version 16. If anyone has insights on this process or tips for flashing software, I’d greatly appreciate your input!
Before you download the control flash, make sure to verify its compatibility. It should be compatible with your device version, specifically ser.A.
I successfully updated my Micrologix 1100 to firmware version 16 using ControlFLASH 12.00.01, which was part of the version 15.02 firmware package. It appears that ControlFLASH 15.01.00 is incompatible with the Micrologix 1100, Series A. Thank you for your assistance, mdim! What steps should I take to determine if a specific version of ControlFLASH is compatible with a given firmware or PLC?
Hey [Your Name], it sounds like a frustrating situation! A common approach when firmware updates get stuck is to try to cycle the power and see if you can re-enter the bootloader mode by holding the Mode button while powering up the PLC. This might allow you to attempt the update again or reset it. Also, ensure that your ControlFlash software is updated; sometimes having the latest version can resolve compatibility issues. If that doesn’t work, check if there are any troubleshooting steps in the Allen-Bradley documentation for your specific model. Good luck, and I hope you can get it back up and running soon!

Answer: When a firmware update fails and the PLC becomes unresponsive, start by ensuring that all connections are secure and that the power supply is stable. If the PLC is stuck at a specific block during the update process and reboots with flashing LEDs, try the following steps: 1. Power cycle the PLC by switching it off and then on again. 2. Attempt to reconnect using RSLogix Micro to see if the device is still responsive. 3. Verify that the USB/RS232 adapter is functioning correctly and that the driver is updated. 4. If possible, try using a different computer or interface to reattempt the firmware update.
Answer: The flashing LEDs below the power button typically indicate an error state or a failed firmware update. This can occur if the update process is interrupted or if there is an issue with the firmware file. In this scenario, the PLC may enter a fault state requiring troubleshooting to restore its functionality. Consulting the device's manual or contacting technical support for specific LED error
