Hi Guys,

Do we have SM0.0, SM0.1, etc in S7 - 300 which we had in S7 - 200 ?? If so, which are those system bits and how to use 'em ?

we Don't have the SM byte in S7-300/400 like S7-200, if you want to used the Clock pulse then Go to the Hardware Configuration -> you CPU Properties -> in that Cycle/Clock Memory -> Enable the Check Box for Clock Memory & define the M memory Area like by default it is 0, for time Period for each Bit you wil find in the help on end of right hand side of the popup.

my be it will help to you.
