The ladder logic programming example uses the M1 START push button input to activate the M1 RUN output. The M1 RUN output is used a second time to latch the M1 RUN output. Both M1 STOP and M1 TOL are wired normally closed (NC) to the PLC inputs and thus need to be configured as normally open (NO) symbols in the logic.
