If there was a SIMATIC Memory Card inserted in the CPU prior to the reset to factory settings,
the CPU loads the configuration contained on the SIMATIC Memory Card (hardware and
software):
• A configured IP address is then valid again.
• If you have backed up adjustment values of absolute encoders on the SIMATIC Memory
Card with the "MC_SaveAbsoluteEncoderData" instruction, these become valid after the
reset to factory settings with SIMATIC Memory Card inserted in the CPU.
