Profibus DP slave - reading/writing parameters

Hallo,
i have attached massflo mass6000 device as profibus dp slave to simatic s7 300. I can read without problem all cyclic data as it is configured through hw configuration. My problem is, that i do not know how to read acyclic data from profibus dp and afaik parameters of that device can be read only acyclically. I have manual with table where are indexes of all parammeters i need to read/write. But i don't know which SFC canbe used for reading that. In HW configuration i have configured massflo as dp slave. It's connected to DP master from S7-300. In slots of that slave i have inserted modules (Actual flow, totalizer, density, temperature) for cyclic reading. These modules can be adressed directly through their IO adresses. Only other definbed adress there is diagnostic adress which is 4093. Profibus DP adress is set to 11. DP slave module can be configured as DPV0 or DPV1. I can choose this from object properties.

Any idea about how i can reach this dp slave parameters by profibus dp?

Thx for any answers or tips.
