hello everybody
i'm pretty new to labview an i've got a question concerning a datastream i'm getting from an s7 simantic.
the datastream looks like the following
#SPSDATA#26|ID=SIMATIC1|DB295.DBB2=0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0#SPSDATA#26|
ID=SIMATIC1|DB295.DBB2=0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0#SPSDATA#26|ID=SIMATIC1|
DB295.DBB2=0,2,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
since this is a tcp connection i'm getting packages and getting e.g. 30 bytes per iteration, converting them into a string an parsing the string.
i wonder what is the best way to be sure to have at least one complete telegram
#SPSDATA#26|ID=SIMATIC1|DB295.DBB2=0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0
because i start from an arbitrary point where i can get
,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0#SPSDATA#26|ID=SIMATIC1|DB295.DBB2=0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
in the first place which mean i've to cut everything before the first valid telegram and then wait for the rest of the ip package or if this is lost
for the next telegram.
i tried to use some kind of patternmatching, since the structure is always the same but it didn't work out.
once i've to the telegram, the processing is not really problem but i'm not sure which VI would suite best for in this case!
maybe someone has a hint how to solve this problem elegant in labview.
thanks andy
