FB details
o_bS_EStop_Out output signal is set to OFF as soon as i_bS_EStopIn input is set to OFF. o_bS_EStop_Out output signal is
set to ON only if i_bS_EStopIn input is set to ON and a reset occurs. If the automatic reset is selected for i_bS_StartReset and
i_bS_AutoReset, reset is not required.
State diagram
State transition of M+SF_ESTOP_R
The signal (o_bS_EStop_Out) may only control the process directly if this does not adversely affect the safety function. In this regard, validate the entire path of
the safety function, including the startup behavior of the process to be controlled.
Note: The transition from any state to the Idle state due to i_bActivate=OFF is not shown. However these transitions have the highest priority (0).
