Data are transmitted on the same physical basis as the trans-
fer of process data to a standard module. The type of data
and their interpretation through the F-device (PROFIsafe
slave) differ.
For PROFIsafe communication in combination with the output
module CPX-FVDA-P2, the following apply:
–
The module supports the PROFIsafe bus profile in the V2
mode
–
Parametrisation on V1 mode is rejected
1.2.2
Process image
Due to the safety mechanisms of PROFIsafe, the output mod-
ule CPX-FVDA-P2 occupies 6 bytes for inputs and 6 bytes for
outputs in the process image of the CPX terminal. Of these, 4
bytes each are used exclusively for PROFIsafe communica-
tion.
The 6 bytes for outputs are made up of the following:
–
2 bytes of output data (F-user data,
Tab. 1/7)
–
1 byte status (for PROFIsafe communication)
–
3 bytes CRC (for PROFIsafe communication)
The 6 bytes for inputs are made up of the following:
–
2 bytes of input data (F-user data,
Tab. 1/8)
–
1 byte control byte (for PROFIsafe communication)
–
3 bytes CRC (for PROFIsafe communication)
