The PROFIsafe I/O module 753-661/000-003 occupies five data bytes in the input
and output process image in the higher-level secure PLC. The secure PROFIsafe
telegrams to send and receive are stored in input and output bytes 0 ... 4.
The process image received different data depending on whether the PROFIsafe
I/O module is operated in PROFIsafe V1 or PROFIsafe V2 mode.
