Step Instructions
Section 3-22
Note Work bits are used as the control bits for A, B, C and D.
3-22-1 STEP DEFINE and STEP START: STEP(008)/SNXT(009)
Purpose
SNXT(009) is placed immediately before the STEP(008) instruction and con-
trols step execution by turning the specified control bit ON. If there is another
step immediately before SNXT(009), it also turns OFF the control bit of that
process.
STEP(008) is placed immediately after the SNXT(009) instruction and before
each process. It defines the start of each process and specified the control bit
for it. It is also placed at the end of the step programming area after the last
SNXT(009) to indicate the end of the step programming area. When it
appears at the end of the step programming area, STEP(008) does not take a
control bit.
