220 PROFIsafe
Fail-safe The FSO application keeps the system in the Fail-safe mode. PROFIsafe
communication is up and running.
This state is reached if a fatal error (for example, CPU test, RAM test, I/O
channel test etc. failed) takes place.
The drive is stopped using the configured method. In the end, the drive
STO is activated. The fail-safe value “0” is set to all I/O channels. The fail-
safe value “0” is transferred to the safety PLC for all I/O channels.
This state can be left only to the Start-up mode by cycling power of the
FSO module or by giving the reset command via the drive (parameter
96.09 FSO reboot, see the drive firmware manual).
PROFIsafe Status Byte bits in the F-Host for the FSO module:
• OA_Req_S = 0
• FV_activated_S = 1
• Device_Fault = 1
ABB_PS1 or ABB_PS2 profile bits in the F-Host for the FSO module:
• FSO_mode.1 = 1
• FSO_mode.0 = 0
• SF_end_ack_req_local = 0
• SF_end_ack_req = 0
• FSO_state =1
See also the Note on page 204.
Configuration The FSO module is in the Safe state. Upon transferring to the
Configuration mode, the FSO answers to one PROFIsafe frame. The fail-
safe value “0” is transferred to the safety PLC for all I/O channels. After
that PROFIsafe communication is not possible. The fail-safe value “0” is
set to all I/O channels.
This state can only be entered from the Fail-safe mode or from any other
state when the drive is not modulating.
This state can be left only to the Start-up mode by cycling power of the
FSO module or by giving the reset command via the drive (parameter
96.09 FSO reboot, see the drive firmware manual).
PROFIsafe Status Byte bits in the F-Host for the FSO module:
• OA_Req_S = 0
• FV_activated_S = 1
• Device_Fault = 0
ABB_PS1 profile bits in the F-Host for the FSO module:
• FSO_mode.1 = 1
• FSO_mode.0 = 1
• SF_end_ack_req_local = 0
• SF_end_ack_req = 0
• FSO_state = 1
