L_DevSMControlDecoder - control signals from the safety module

The SM3xx safety module uses the bit-coded control signal SM_dwControl of the

SB LS_SafetyModuleInterface to transmit information about requested or active safety functions to

the application. The FB decodes the control signal into individual boolean control signals for further

use in the FB interconnection.

• 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".

• Several safety functions can be requested/be active at the same time.
• The safety functions that are supported depend on the safety module used.
• The FB functionality corresponds to a "DWORDBOOL" converter, but the boolean outputs of

the FB are called according to their meaning.
