A200.12 (Step Flag) is turned ON for one cycle

when STEP(008) is executed. This flag can be

used to conduct initialization once the step

execution has started.

Normal ladder

• The control bit, B, must be in the Work Area for STEP(008)/SNXT(009).

• A control bit for STEP(008)/SNXT(009) cannot be use anywhere else in the ladder diagram. If the

same bit is used twice, as duplication bit error will occur.

• If SBS(091) is used to call a subroutine from within a step, the subroutine outputs and instructions will

not be interlocked when the control bit turns OFF.

• SNXT(009) will be executed only once, i.e., on the rising edge of the execution condition.

• Input SNXT(009) at the end of the step program area and make sure that the control bit is a dummy

bit in the Work Area. If a control bit for a step is used in the last SNXT(009) in the step program area,

the corresponding step will be started when SNXT(009) is executed.

ON for one cycle when a step program is started using STEP(008). Can be used to reset

timers and perform other processing when starting a new step.

Step a starts when C turns ON

When d turns ON, b starts (A is interlocked)

e turns ON (B is interlocked)
