 MELSEC iQ-R Safety Function Block Reference
In this example, an enabling switch with no monitor signal for position 3 is used. Therefore, SA\SM400 (Always on) is
connected to the input signal, i_bS_EnableSwCh2, of M+SF_ENBLSW_R.
When using an enabling switch with monitor signal for position 3, connect the signal to i_bS_EnableSwCh2 to monitor the
status of position 3.
