Has anyone experienced and found out the reason why values which are received from DCP and traced in TIA drop to zero for exactly one sample (but many times).

I hope the picture makes it clear what I mean.

I found this topic:
https://support.industry.siemens.com/forum/us/en/posts/starter-trend-dropping-out/272392/
but it covers trend in Starter so I am not sure they are related at all.

1. Check with Starter trace, whether you face the same penomenon.
   If yes, then it is a control issue. ==> Check wiring, components and parameterisation.
2. If no, than it is a transmission issue.
   1. If it is an acyclic transmission, then it is a non relyable value, because the transmission works, when there is enought calculation time left.
   2. For monitoring and operation cyclic transmission is required.
      Please follow the telegram setup according DCPs manual section 7.4.3 cyclic transmission.
      Unfortunately everything has to be done by hand.
   3. Further adapt and play with the cycletime a little bit. Even it is no IRT and not synchonised, the goal is to get every cycle a valid new value
