ctrlX CORE X3 and EFC, max size of process data

I'm trying to find the maximun number of IDN's and bytes for the ethercat communication for the EFC.

This data is avaiable in the brief description of the IndraDrive manual, but haven't found this for the EFC.

For the IndraDrive with FW20 it says this:

  • Max. length of the configurable MDT/AT data, 15 IDNs with max. 48 bytes; if bus clock = position clock, the max. length is reduced by half to 24 bytes

Whats the limits for the EFC?

It's the same limit as in profinet, ie 30 bytes:
