Implementation of safety requirements from applicable standards

The safety-related function block has been developed according to the safety requirements (from applicable standards) listed in this section. All other requirements from these standards must be observed when implementing the safety-related function.

This section describes either how the function block meets the requirements of the standards or what measures need to be taken to meet the requirements of the standards.

Standards	Context/Requirement	Implementation
EN ISO 12100-2	Start-up after failure of supply voltage/spontaneous restart	The function block supports a start-up inhibit and/or restart inhibit of the function block after start-up of the Safety Logic Controller or activation of the function block (S_StartReset = SAFEFALSE) the ESPE that was previously triggered is no longer triggered (S_AutoReset = SAFEFALSE) You are responsible for planning and implementing the start-up/restart behavior according to your risk analysis. To prevent an unintended start-up/restart, you may need to perform an additional function start once the safety-related function has been reset. This will depend on both the results of the risk analysis and the signal path of the reset signal.
EN ISO 13849-1	Manual reset device	The Reset input supports the function of a manual reset device. NOTE: Resetting does not occur with a negative (falling) edge, as specified by the EN ISO 13849-1 standard, but with a positive (rising) edge.
EN ISO 13849-1	Category B to 4	Single-channel or two-channel connection must be established depending on the category. NOTE: Cross-circuit monitoring is not performed by the function block. It is your responsibility to implement this monitoring function outside of this function block in the safety-related control system. For example, an appropriate function block (Equivalent or Antivalent) must be connected upstream for the purpose of using two-channel ESPE.
EN 60204	Stop functions	The function block (S_ESPE_Out enable signal) executes stop category 0.
EN 61496-1	Start-up inhibit function	The function block supports a start-up inhibit and/or restart inhibit of the function block after start-up of the Safety Logic Controller or activation of the function block (S_StartReset = SAFEFALSE) the ESPE that was previously triggered is no longer triggered (S_AutoReset = SAFEFALSE) You are responsible for planning and implementing the start-up/restart behavior according to your risk analysis. To prevent an unintended start-up/restart, you may need to perform an additional function start once the safety-related function has been reset. This will depend on both the results of the risk analysis and the signal path of the reset signal.
