2.5.2.3
Control information
Via the bit-coded control signal SMI_dwControl of the SB LS_SafetyModuleInterface the SM301
safety module transmits information about requested/active safety functions to the application.
• Several safety functions can be requested/active at the same time.
Bit coding of the SMI_dwControl status signal
Bit
Name
Meaning
1 SS1 active
function is active.
• After the parameterised stopping time has elapsed, bit 0 of the status signal
SMI_dnState (STO active) is set.
2 SS2 active
function is active.
• After the parameterised stopping time has elapsed, bit 16 (SOS monitored) is set.
3 SLS1 active
• After the parameterised braking time Nlim1 has elapsed, bit 8 of the status signal
SMI_dnState (SLS1 monitored) is set additionally.
4 SLS2 active
*
• After the parameterised braking time Nlim2 has elapsed, bit 9 of the status signal
SMI_dnState (SLS2 monitored) is set additionally.
5 SLS3 active
*
• After the parameterised braking time Nlim3 has elapsed, bit 10 of the status
signal SMI_dnState (SLS3 monitored) is set additionally.
6 SLS4 active
*
• After the parameterised braking time Nlim4 has elapsed, bit 11 of the status
signal SMI_dnState (SLS4 monitored) is set additionally.
7 SDIpos active
**
Safe positive direction (SDIpos)
• After the parameterised SDI delay time has elapsed, bit 12 of the status signal
SMI_dnState (SDIpos monitored) is set additionally.
8 SDIneg active
**
Safe negative direction (SDIneg)
is active.
• After the parameterised SDI delay time has elapsed, bit 13 of the status signal
SMI_dnState (SDIneg monitored) is set additionally.
9 ES active
function for motion functions in special operation is active.
10 SLI is active
***
"Safely limited increment (SLI)" function is active.
11 OMS
function for special operation is requested.
16 SOS active
"Safe operating stop" (SOS) function is active.
• The safe operating stop is monitored.
• The function will be active after the function
has ended.
23 SSE active
is active.
• Depending on the parameterisation of the emergency stop function, bit 1 (SS1
active) or bit 0 of the status signal SMI_dnState (STO active) is set after the
function has ended.
29 OMS active
*
Special operation is active.
* From SM301 V1.1 ** From SM301 V1.3 *** From SM301 V1.4
Bits not listed are reserved for future extensions!
Note!
To effect the corresponding action (e.g. braking to standstill, holding the standstill
position), the application engineer has to provide an appropriate interconnection in the
application.
• To integrate the basic function "Limiter", the output SMI_dwControl is to be
connected to the input LIM_dwControl of the LS_Limiter system block.
