Firmware Update Error in Roll Forming Machines – Causes, PLC or Drive Update Failures, Inspection & Repair Guide
Firmware Update Error
Roll Forming Machine Electrical & PLC Failure Guide
Firmware update error is a control system problem in roll forming machines where a firmware upgrade for a PLC, servo drive, VFD, HMI, or other control device fails or becomes corrupted during installation.
Modern roll forming machines rely on embedded firmware inside many control components. Firmware is the low-level software that controls how electronic devices operate and communicate.
Firmware is commonly found in:
PLC processors
servo drives
variable frequency drives (VFDs)
HMI operator panels
communication modules
safety controllers
industrial network devices
Manufacturers periodically release firmware updates to:
fix software bugs
improve machine performance
add new functions
improve communication compatibility
enhance safety or security features
Firmware updates are typically installed through engineering software, USB devices, Ethernet connections, or memory cards.
However, if the update process is interrupted or performed incorrectly, the firmware may become incomplete or corrupted.
This condition is known as a firmware update error.
Firmware update errors commonly affect roll forming machines producing:
metal roofing panels
metal wall cladding panels
standing seam roofing systems
structural deck profiles
C and Z purlins
light gauge steel framing components
Typical production symptoms associated with firmware update errors include:
PLC failing to start
servo drives showing firmware fault alarms
HMI screens not booting correctly
communication between devices failing
machine refusing to start after update
unexpected device resets
In severe cases, firmware corruption may prevent the control device from operating at all.
Proper update procedures and reliable power supply are essential when updating firmware.
Causes of Wear or Failure
Firmware update errors usually occur due to interruptions during the update process or incorrect update procedures.
Several factors may contribute to this condition.
Power Loss During Update
Unexpected shutdown may corrupt firmware installation.
Incorrect Firmware Version
Installing incompatible firmware may cause system faults.
Communication Interruptions
Network failure during updates may interrupt data transfer.
Improper Update Procedure
Skipping required update steps may cause errors.
Faulty Storage Devices
Corrupted USB drives or memory cards may contain damaged firmware files.
Incomplete File Transfer
Partially transferred firmware files may cause installation failures.
Why It Happened and What Caused It
From a control system engineering perspective, firmware updates replace the internal operating code stored in a device’s non-volatile memory.
During the update process, the device temporarily removes the existing firmware and writes the new firmware to its memory.
If the update process is interrupted before the new firmware is fully written, the device may be left without a complete operating program.
This can prevent the device from booting or functioning correctly.
Firmware updates often rely on stable communication channels and uninterrupted electrical power.
If network communication fails or if the device loses power during the update process, the firmware may become corrupted.
Additionally, installing firmware designed for a different device model or hardware version may cause compatibility errors.
Following proper update procedures helps prevent firmware corruption.
How to Inspect the Problem
Inspection Procedure
Diagnosing firmware update errors requires inspecting the control system and reviewing update logs.
Step 1 – Check Device Status Indicators
Observe LEDs indicating device startup or fault conditions.
Step 2 – Review Update Error Messages
Check engineering software or HMI diagnostics.
Step 3 – Verify Firmware Version
Confirm that the correct firmware version is installed.
Step 4 – Inspect Communication Connections
Ensure stable network connections during updates.
Step 5 – Inspect Update Files
Verify that firmware files are complete and uncorrupted.
Step-by-Step Technician Guide – How to Fix
Correcting firmware update errors typically requires reinstalling firmware or restoring device software.
Method 1 – Restart the Device
Power cycle the device to attempt a normal boot.
Method 2 – Reinstall Firmware
Upload the correct firmware version again.
Method 3 – Use Recovery Mode
Many devices provide firmware recovery procedures.
Method 4 – Verify Firmware Compatibility
Ensure the firmware matches the device model.
Method 5 – Replace Faulty Hardware
If firmware cannot be restored, the device may require replacement.
Preventative Maintenance Tips
Preventing firmware update errors requires careful planning and proper update procedures.
Maintain Stable Power Supply
Avoid performing updates during unstable power conditions.
Use Verified Firmware Files
Only use firmware provided by the equipment manufacturer.
Follow Manufacturer Update Procedures
Correct installation steps prevent update failures.
Backup System Configurations
Backups allow recovery if updates fail.
Test Updates Carefully
Perform updates during planned maintenance periods.
