NOTE:
The TFTP Server must be on the same IP subnet as the 2572-A module.
NOTE:
Avoid updating the 2572-A while HMI or other clients are attempting to communicate with the module.
This will slow the file download considerably and may cause the download process to terminate
without completion.
Firmware Update Process
The update process consists of two phases. In phase one, the firmware files are downloaded from the
TFTP server, verified, and stored in the module RAM. If all downloaded firmware files are
successfully verified, phase two replaces the current firmware stored in flash with the newly
downloaded firmware. This two phase procedure minimizes the possibility of corrupting the existing
firmware during the download process.
Phase One
After you click on the download button the module will reset. Once the LED test sequence is
complete, the MS LED will begin blinking green. Once the file download from the TFTP server starts
the NS LED will illuminate. If you are downloading application firmware, this process will take about
60 seconds. If you are downloading new bootloader code, this should take about 15 seconds.
If phase one does not complete successfully, the application firmware currently stored in flash will be
restarted. To alert you of this condition, the MS LED will flash green and red. You should access the
event log to determine the cause of the problem, make corrections, and the reinitiate the download
process. See the section on Troubleshooting Download Problems
Phase Two
Once the downloaded file has been verified, the firmware stored in flash will be overwritten by the
newly downloaded firmware. If you are downloading application firmware this should take about 30
seconds. If you are downloading new bootloader code, this will take only a couple of seconds.
To indicate that the module is updating flash, the MS and NS LEDs will each alternate between green
and red after each sector is written. Once the flash has been completely updated, the module will reset
and start up with the new firmware.
NOTE:
While the flash is being updated, do not remove power from the module or else the application
firmware in flash will be corrupted.
Once the module has restarted, you should confirm that the desired version of firmware has been
loaded by accessing the Module Information web page. The event log will also contain messages that
indicate the download completed successfully.
If you should corrupt the existing application firmware by interrupting the flash update, the module
will stop with both the MS and NS steady red. To attempt recovery, reset the module. Once reset, the
module will attempt to download new application firmware from the same location used the previous
time.
