Faster Update Rate 800xa - OPC DA - PLC Connect

Hi Experts!

For 50 Real values we would like to have a increased update rate in 800xA. It is now set to 1000ms in the Real PCA.

We tried:

to increase the update interval in the signal configuration for the specified tag > 10ms
to increase the refresh rate of a graphic display > 10ms
to increase the Kepware OPC update rate > 10ms

None of the above worked, somehow when looking at the live values in the Real PCA the update rate is set and stuck to 1000ms. Is it possible to make the update rate for a select amount of tags 100ms or faster? How can this be done?
