I do have a couple of variables inside my project, which are working very fine when I start my zenOn runtime. But when I watch my CEL, I can see that there are some variable permanently protocolled. Even when their value doesnīt change.
It might be that those variables are not stable inside the PLC. They change theirs value very quickly, that it canīt been seen inside a normal dynamical element.
To make sure of this behavior, the easiest was is to create a dummy-archiv and add these variables. (set the archive to spontaneous!)
Then you should be able to see very clearly if such non-stable variables cause this effects.

If there is no chance to solve this problem inside your PLC, you can try it via the "zenOn-hysteresis". Itīs exactly for such cases.
