alvr Posts: 21 Rating: (0)	Hello, Is S7-1200 CPU able to catch any extern digital (rising or falling edge) signal and start immediate (not at next program cycle) interrupt function which can service it? I am using even microcontrolers and this external hw interrupt is base feature. Is it able to even with S7-1200. Thank you very much.

On page 190 of the s7-1200 system manual (https://support.automation.siemens.com/WW/llisapi.dll?query=s71200+system+manual+04%2F2012&func=cslib.cssearch&content=adsearch%2Fadsearch.aspx%3Ftab%3D2&lang=en&siteid=csius&objaction=cssearch&searchinprim=_searchinprim_&nodeid=99&x=16&y=8&cssearchengine=NEW&x=0&y=0) it documents the answer to your question - and in that same portion of the manual describes how to enable and use it.
