The above programming is used when steps A and B cannot be executed
simultaneously. For simultaneous execution of A and B, delete the execution
conditions illustrated below.
0.02 0.01
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-Program-
mer. 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.
