Hello guys,
CPU 314 fails (Blackout). I replaced the CPU by new and fixed back mmc card to the slot and power up the main power and observed CPU is ready and it is run mode.I run the machine and observed working and switch off the main power and switch on again and observed machine is not starting then I download the back up program from my PC and restored normal operation.
Now I am curious to learn what is the main function of mmc card.why I have to download the backup program to the new cpu.? As far as I learn from realpars video tutorial but still concept is not clear.
Conclusion, congratulation to real pars team.Because of realpars team I learn something from them and I applying to my job.Thank you for your support and help.
Kind regards.
But I Bishara.
When the original CPU failed, you took out the MMC Card and put it in the new CPU and it worked fine. Then, after cycling power on the new CPU, the program did not work.
It is possible that after the sudden shutdown in power, working memory in the CPU or the program on the MMC was not initialized correctly. Whenever I have a power loss, when the power is restored, I like to do a manual reset on the CPU. That should allow the MMC program files to be recognized correctly.
Now that power has been restored and the program loaded, do a manual reset to insure that the program image on the MMC card is good.
