10.3.2 I/O status information

Via the bit coded status signal SMI_dnIoState of the LS_SafetyModuleInterface SB, the SM3xx

safety module transmits the status of the safe inputs and outputs 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_dnIoState to the L_DevSMStateDecoderIO FB which is available in the function

library from V2.0.

10.3.3 Control information

Via the bit coded control signal SMI_dwControl of the LS_SafetyModuleInterface SB, the SM3xx

safety module transmits information on safety functions requested, or on active safety functions to

the application.

• Several safety functions can be requested/active at the same time.

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

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 acknowledgement via terminal effected (negative edge: 10).

6 AIE Error acknowledgement via terminal effected (negative edge: 10).

8 PS_AIS Restart acknowledgement via safety bus effected (positive edge: 01)

9 PS_AIE Error acknowledgement via safety bus effected (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!

The corresponding actions (e.g. braking, braking to standstill, holding of the standstill

position) must be executed by the application, e.g. via the basic function "Limiter

".

( 502)

• 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.
