I have free slots there, and I would like to insert a new digital output module (6ES5-451-7LA11). What shall I do? How and what and where do I configure it? What is the right order to switch off and on the power supply, how can I avoid the deletion of the working program? sorry for the lots of question, but I do not know what to do, and have not found the right manuals. Thanks!! C

You did not say if your CPUhas an EPROM in it or relies on a backup battery tokeep the program in case of power failures. Either way, it never hurts toupload an online backup from the CPUprior to poweringthe PLC off. I hope this helps

Hello pici_c you do indeedunderstood it correctly. S5 I/O addresses are either fixed (Slot based) and/or done via DIP Switches (on the I/O card itself or via the IM as in your case)and there is no "HWconfig" like Step7 has (135 and/or 155 systems can additionally have a so called "Address list' DB, but this too does not exist in your 115U944 CPU). Your responsibilty is however to make sure to find a free address range for the new card. I hope this helps
