PROFIsafe 207
Note: The states of all FSO inputs and outputs are shown in the PROFIsafe
message. These states also show the states of SBC outputs and feedback inputs.
ABB_PS2 profile F-Output user data
This table shows the bit order of the F-Output data, which is included in the
PROFIsafe message sent to the FSO module from the safety PLC. For all the bits in
the F-Output data, one (1) means active and zero (0) non-active.
Intege
r16
6 Safe_speed_MSB The current motor speed value from FSO (MSB).
Intege
r16
7 Safe_speed_LSB The current motor speed value from FSO (LSB).
*)
The safety PLC must ignore the value of the reserved bits. This ensures the compatibility
with future versions of the PROFIsafe profile where the reserved bits may be used.
