Hello,

I am having a problem with my VK 45 II with seicos M3 controller. It started a couple of weeks ago showing randomly NUMC board error on a daily basis both when the machine was running a part or on standby. This made the machine go on e stop.
Starting today when ever I press MDY button on the panel the error appears :NUMC SYSTEM FAIL, Software error occurs in the NUMC board . All the other machine functions and buttons work ok, but I can't start a program in memory mode.
The machine data and parameters are ok, I even scrolled trough the ladder diagram to check for changes but nothing. When the error occurs there are 2 red led s on the NUMC board number 3 and 5.

Thank you
