Can I do that (with the plc running) with "edit ethernet station" of Step 7 or i must download the HW and the cpu will go to stop? Thank you very much! Best regards, Gonzalo

Best you check manual for more detailled information about changing IP-Address (i.E. Page 59) PROFINET CP 343-1 Manual Manual part B Regards, Towome

How can you configure an S7 CP during runtime? Forum Best regards, Gonzalo
