Step Instructions
Section 3-22
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.
Note
In the above example, where SNXT(009) is executed for W00002, the branch-
ing 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.
Step (A) ladder program
Step (B) ladder program
Step (C) ladder program
Step W00000
(A)
Step W00001
(B)
