10.3.1 Status information

Via the bit-coded status signal SMI_dnState of the LS_SafetyModuleInterface SB, the SM3xx safety

module transmits the status of safety functions to the application.

• Which bits are supported depends on the safety module used.

 Tip!

For decoding the status signal into individual boolean status signals, simply connect the

output SMI_dnState to the L_DevSMStateDecoder FB which is available in the function

library from V2.0.
