Hi,
I’d like to control the sample time of output so that this output under some conditions comes out only once. Now there are many same outputs.
Is “IsSampleHit” for this purpose?
I got an error if I use this line:
if block.InputPort(1).IsSampleHit
‘IsSampleHit’ cannot be called for a port that has no sample time.
Are there any conditions that must be fullfilled to use ‘IsSampleHit’?
Thanks Senmeis

I think you need to have specified a port-based sample time for that input. Also, here is the documentation for IsSampleHit.
