2.5.2.2 I/O status information
Via the bit-coded status signal SMI_dnloState of the SB LS_SafetyModuleInterface the SM301
safety module transmits the status of the safe inputs and the safe output to the application:

Tip!
For decoding the status signal into individual boolean status signals, simply connect the
output SMI_dnIoState to the L_DevSMStateDecoderIO FB which is available in the function
library from V2.0.
[2-2] Example: Decoding of the SMI_dnIoState status signal into individual boolean status signals
Bit coding of the SMI_dnIoState status signal
Bit Name Meaning
0 SD-In1 Sensor input 1 in ON state.
1 SD-In2 Sensor input 2 in ON state.
2 SD-In3 Sensor input 3 in ON state.
3 SD-In4 Sensor input 4 in ON state.
5 AIS Restart is acknowledged via terminal (negative edge: 10).
6 AIE Error is acknowledged via terminal (negative edge: 10).
8 PS_AIS Restart is acknowledged via safety bus (positive edge: 01).
9 PS_AIE Error is acknowledged via safety bus (positive edge: 01).
12 SD-Out1 Safe output 1 (feedback output) in the ON state.
Bits not listed are reserved for future extensions!
Note:
This connection example only shows the status signals of the FB L_DevSMStateDecoderIO supported by SM301
V1.1.
