204 PROFIsafe
ABB_PS1 profile F-Input user data
This table shows the bit order of the F-Input user data, which is included in the
PROFIsafe message sent from the FSO module to the safety PLC. For all the bits in
the F-Input data, one (1) means active and zero (0) non-active.
Note: In the Fail-safe and Configuration states, all the bits in the PROFIsafe message
are set to “0”. In these cases, you can read the FSO state from:
• Siemens PLC: bits QBAD and PASS_OUT in the PROFIsafe data block
• ABB PLC: bit Device_Fault in the PROFIsafe data structure.
See also section FSO module modes and states on page 212.

0 0 SLS2_active SLS2 (Safely-limited speed) is active. Active
when the SLS2 function is active and the motor
speed is below the SLS2 limit (that is, when the
SLS2 monitoring is on).
1 SLS1_active SLS1 (Safely-limited speed) is active. Active
when the SLS1 function is active and the motor
speed is below the SLS1 limit (that is, when the
SLS1 monitoring is on).

The value is 0. Must be ignored by the F-Host.
4 SS1_active SS1 (Safe stop 1) is function active.
5 SSE_active SSE (Safe stop emergency) function is active.
6 SBC_active SBC (Safe brake control) function is active.
7 STO_active STO (Safe torque off) function is active.
