When putting a program card into the PLC, the existing program is wiped and the program on the card is used instead. With a program card, the card must remain in the PLC. Without the card the PLC is without a program. So the question now.. how do you extract the data log?.. web services or via direct card transfer? My personal preference is with creating a transfer card. The twist is that some critical code blocks can be bound to a specific CPU serial number so that the card can only be used for [that] specific CPU. There is free software available from Siemens with which a PLC program can be loaded with. The MMC card route and TIA software are not your only options. Your thoughts?

Hi,
please read this or in the manual chapter 5.5
To use a program card with your CPU, follow these steps: 1. Insert the program card into the CPU. If the CPU is in RUN mode, the CPU goes 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 CPU reboots and evaluates the program card, the CPU erases the internal load memory of the CPU. The CPU then goes to the start-up mode (RUN or STOP) that you configured for the CPU. The program card must remain in the CPU.
