Additional Information:

• In the above example, where SNXT(009) is executed for W0.02, the branching moves onto the next
steps even though the same control bit is used twice. This is not picked up as an error in the program
check using the CX-Programmer. A duplicate bit error will only occur in a step ladder program only
when a control bit in a step instructions is also used in the normal ladder diagram.
• The above programming is used when steps A and B cannot be executed simultaneously. For simul-
taneous execution of A and B, delete the execution conditions illustrated below.
