Hi guys,

Anybody know how to SRAM expansion from 256KB to 1MB?The control system is FANUC 16i-MA.
I tied to replace the hardware, it is not feasible. May be need to update the system software.

Thanks,
Aaron

Check with memoryman or memex for non fanuc upgrades, or of course call fanuc. Fanuc will probably be 2-4x more expensive, but they do it for you, rather than sell the memory and provide instructions.

Also if your daring, you might already have a larger than 256KB module installed that you could just enable if you know how.
NOTE: see forum rules on posting such info.

Thank you for the reply.
I contacted FANUC last week, they said need the machine factory to contact the FANUC of Japan to get the authorization before the can upgrade function.That is too trouble.
We have the 1MB SRAM module,so I want to know how to make it work.

Thanks,
Aaron

a 1mb module will give you 512k (1280m) usable part program storage.
Turning it on is easy and free. we also sell a 3mb module to give 2MB (5120m) usable part program storage.

I want to know how to use the large memory module working in the old FANUC control system,the system doesn't recognize the new memory module,may be should update system software. Do you have the system software files can be applied to 1MB module?

thanks

after installing the larger memory module you need to change a secret parameter.
see the RED text above.....

You have to change the appropriate option bits; We don't keep options secret.
We don't ever charge for software options.

[fordav11]

I mean secret 'here' of course... red text etc.

[Aaron liang]

I know FANUC secret parameter(9921.0~9921.4),but to no avail.
The problem is the 256KB module's SRAM file name is “SRAM256A.FBD” ,but the 1MB module have two SRAM files,"SRAM1-0A.FBD"and "SRAM1-0B.FBD".Even if the hardware replacement 1MB module,but the backup file does not recognize.
Someone know please tell me.

thanks,
Aaron

To get this straight: you replaced the 256k module with the 1M module and are trying to restore using the SRAM256A.FBD file?
I will on Friday tell you how to do that.

Yes,I would like to do.
Thank you very much.
Look forward to your reply.:wee:

You can just clear the memory and reinstall all the files, then turn on the extra memory.
The alternate way is: you need a text editor that can do hex editing.
Then open the SRAM256A.FBD file and pad it with zeros, until the file is 512k long.
Save it as SRAM1-0A.FBD, create a new file with only zeros, also 512k long and name that SRAM1-0B.FBD. Then use these files to update the 1M module.
Also change the options. If you email the SRAM256A.FBD file, I will generate the two files for you.

Have you done the similar things?
This monday,I installed the 1MB module on the old machine and loaded the new machine's SRAM file(SRAM1-0A.FBD and SRAM1-0B.FBD).But have a alarm that display"930 CPU INTERRUPT" when restart the controller.So I think may be should update software or change the secret parameter.
The attachment is the SRAM file.
Thank you for your hlep. please reply as soon as possible.

Best Regards,
Aaron

SRAM file
（Site does not recognize the FBD file formats.）

[fordav11]

there's an easier way.
use HEX editor to create an empty 256k binary file.
then at the DOS prompt....

copy /b SRAM256A.FDB + 256.bin SRAM1-0A.FBD
copy /b 256.bin + 256.bin SRAM1-0B.FBD

see attached files

Yes, you right.
Dou you think these file can be run directly on the controller?
Thanks,

[Aaron liang]

What model of Fanuc, can you use DNC?

FANUC 16i-MA

We don't like to use DNC,so .....

[fordav11]

ignore what cncmakers001 said. its not even related to this topic.

the SRAM files need to be restored into the controller through the IPL screen usually via a memory card.

[Aaron liang]

I use other machines SRAM backup file loaded in the controller,But have a alarm when restart the controller.It's display"930 CPU INTERRUPT".

[fordav11]

The manual says...
930 CPU INTERRUPT CPU error (abnormal interrupt).
The motherboard or CPU card may be faulty.

Clear all memory (hold RESET and DELETE on power-on) and re-load parameters/PMC parameters etc. If the error still happens then you have a hardware problem.
