Can I add an output card for PLC S7-300? How i make a programming this card? please can your help me to find reference manual about this?

You can add an output providing there is room in the rack for it. Once you have decided on the type you can obtain a manual for it from the Simens Automation website. Configuration is under the Hardware Configuration heading where you need to add I/O mapping.
