￭ FSPS-21 PROFIsafe profiles
The content of the F-Input and F-Output user data is configured with FSPS-21 specific
PROFIsafe profiles. The FSPS-21 module supports the ABB_PS3 profile.
The ABB_PS3 profile provides the functionality to control and monitor the safety functions.
ABB_PS3 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 FSPS-21 module to the safety PLC. For all the bits in the F-Input
data, one (1) means active and zero (0) non-active.
