NJ controller firmware upgrade.

Is it possible to upgrade the firmware in an NJ controller?

I recall that the cleanest/recommended method to upgrade firmware was to send the processor to OMRON to perform this change.

This firmware upgrade method may have changed but I am not sure.

Can any OMRON guys shed light on this?

Yes, either that, or an Omron engineer can do it at your facility.

Thanks.

To that end, I have an Omron rep visiting me this week to do the upgrade.

NJ Firmware can be update using SD card, You first have to write firmware files using  DDWin..... Also you will require a file as per the series like NJ301 has a different file and NJ501 has a different file.

Yes, but Omron's policy is that the user will not do this process (Using DDWin) as there is a potential to make a brick of the controller. Omron will actually sell the firmware already installed on an SD card that comes with a step by step procedure to update the firmware.  This will lessen the likelihood of damaging the processor.

Reminds me of Siemens...  S7 1200 .. :-)    And, I'm going to Omron to get away from Siemens.

Quite a big difference between S7-1200 and NJ.

You need to go through the Omron rep to upgrade firmware, it's not something you can download on your own.

Perhaps I can help ..  I said earlier .."And, I'm going to Omron to get away from Siemens."  

This implied no comparison between Omron NJ and Siemens S7-1200 .. they are quite different after all...  However, where they are NOT different, Is the complex and expensive manor that firmware upgrades are performed ...  I think Crossbow thought I was comparing the CPU's  :-)

No, I was not referring to CPU, but to firmware upgrade.  There is typically no need to upgrade firmware in a controller once it is installed.  You buy a CPU because it has the features you need.  You don't plan to update the firmware if the application is already solved.

Only reason to upgrade a working installed CPU is if there is a bug in it.
