I moved the blocks to the memory card using a PG
But when i insert the memorycar in the slot the plc mode goes to stop (flashing)
when i clear the plc ...insert the memory card..doownload the block ..it works fine..even after shutting down power the memory card does what it has to do
when i remove the card same story ..flashing in stop mode

Why does the PLC goes to stop ? if i do it this way i have a problem when the program get changed ...the PLC will have to go to stop each time i have to make a change on the Memory card.
thanx !
