PROFIsafe version 2.6

For safe communication, CSB..A safety options need a total of 9 bytes for input data and 8 bytes for output data for the PROFIsafe telegram part and occupy them in the process image. Of these, 4 bytes of input data and 3 bytes of output data are the actual safe I/O data (F-reference data). The module with the designation F-I/O‑module (4/3 bytes) V2.6 is required for data exchange via PROFIsafe with the CSB..A safety options.
