Hello,

I have old Burkhardt+Weber portal milling machine Hyop 750 with CNC Sinumerik 8 and PC Simatic S5 150S. PC stopped and two LEDs are lighting on6ES5926 card - STOP(red) and COLD RESTART REQUIRED(orange). After clearing the PC RAM area with PG675 and switching PC from STOP to START green LED lights (no red and orange), but PC not works - any output to machine. Do this action rewrites PC programme from EPROM to RAM or I need to rewrite it separately? Thanks.
