PROFIsafe input data
The safety module transmits the PROFIsafe input data to the controller. This can be
displayed via "Safety function status" (C15000).
Bit coding of PROFIsafe input data
Bit Name Description
0 STO active The STO function is active and the drive is safely switched to torque−free
operation.
This bit is also set at the end of the stopping time by SS1.
1 SS1 active The SS1 function is active.
At the end of the function the STO bit is set.
2 SS2 active The SS2 function is active.
At the end of the function the SOS bit is set.
3 SLS1 active The SLS1 function is active.
At the end of the function the SLS1_monitored bit is set in addition.
4 SLS2 active The SLS2 function is active.
At the end of the function, bit SLS2_monitored is set in addition.
(as of
SM301 V1.1)
5 SLS3 active The SLS3 function is active.
At the end of the function, bit SLS3_monitored is set in addition.
(as of
SM301 V1.1)
6 SLS4 active The SLS4 function is active.
At the end of the function, bit SLS4_monitored is set in addition.
(as of
SM301 V1.1)
7 SDIpos is active The SDIpos function is active.
After the deceleration time has expired, bit 21 (SDIpos monitored) is set in
addition.
(As of SM301 V1.3)
8 SDIneg is active The SDIneg function is active.
After the deceleration time has expired, bit 22 (SDIneg monitored) is set in
addition.
(As of SM301 V1.3)
9 ES active 1: ES function in special operation is active: Motion function
0: ES function in special operation is not active: Stop function
10 SLI is active The safely limited increment (SLI) function is active. (As of SM301 V1.4)
11 OMS 1: special operation requested
0: normal operation
16 SOS monitored The SOS function is monitored.
17 SLS1 monitored The SLS1 function is monitored.
18 SLS2 monitored The SLS2 function is monitored. (as of SM301 V1.1)
19 SLS3 monitored The SLS3 function is monitored. (as of SM301 V1.1)
20 SLS4 monitored The SLS4 function is monitored. (as of SM301 V1.1)
21 SDIpos is monitored The SDIpos function is active, the compliance with the direction of
movement is monitored.
(As of SM301 V1.3)
22 SDIneg is monitored The SDIneg function is active, the compliance with the direction of
movement is monitored.
(As of SM301 V1.3)
23 SSE active The SSE function is monitored.
At the end of the function the STO or SS1 bit is set according to the
emergency stop function parameterised.
