Hi @MaP just to add to what @joeamiraglia said, if you are using a persistent TCP pair then you should either override the permissions or change them from the publishing mango instance. if they are not overridden and you change them on the receiving end, then the next time the pair syncs they will revert back to the permissions configured on the publishing instance.

I personally prefer changing them at the publishing instance as this does not affect the data point runtime, so events will not get reset.
