To transfer the program to a CPU, follow these steps:
1.
Insert the transfer card into the CPU (Page 100). If the CPU is in RUN, the CPU will go to
STOP mode. The maintenance (MAINT) LED flashes to indicate that the memory card
needs to be evaluated.
2.
Power-cycle the CPU to evaluate the memory card. Alternative methods for rebooting the
CPU are to perform either a STOP-to-RUN transition or a memory reset (MRES) from
STEP 7.
3.
After the rebooting and evaluating the memory card, the CPU copies the program to the
internal load memory of the CPU.
The RUN/STOP LED alternately flashes green and yellow to indicate that the program is
being copied. When the RUN/STOP LED turns on (solid yellow) and the MAINT LED
flashes, the copy process has finished. You can then remove the memory card.
4.
Reboot the CPU (either by restoring power or by the alternative methods for rebooting) to
evaluate the new program that was transferred to internal load memory.
The CPU then goes to the start-up mode (RUN or STOP) that you configured for the project.
Note
You must remove the transfer card before setting the CPU to RUN mode.

Program card
CAUTION
Electrostatic discharge can damage the memory card or the receptacle on the CPU.
Make contact with a grounded conductive pad and/or wear a grounded wrist strap when
you handle the memory card. Store the memory card in a conductive container.
Check that the memory card is not write-protected. Slide the protection
switch away from the "Lock" position.
Before you copy any program elements to the program card, delete any
previously saved programs from the memory card.
