2.5.2.1 Status information
Via the bit-coded status signal SMI_dnState of the SB LS_SafetyModuleInterface the SM301 safety
module transmits the status of safety functions to the application.

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.
