of output coils should be avoided. The No. of output coil used by a step should also avoid being used when the step ladder diagram returns to a general ladder diagram.

Repeated usage of timer:

See the opposite diagram. Timers can only be used repeatedly in non-adjacent steps.

Transfer of Step Points:

SET Sn and OUT Sn instructions are used to enable (or transfer to) another step. Because there can be many step control sequences (i.e. the initial steps starting with S0 ~ S9) existing in the program. The transfer of a step can take place in the same step sequence, or be transferred to different step sequence. Usages of SET Sn and OUT Sn are different according to the transfer methods. Please see the explanations below

SET Sn

Used for driving the next step in the same sequence. After the transition, all output in the previous step will be OFF.

X0

SET S12

S12

Y1 X1

SET S14

OUT Sn

When SET S12 executes, S10 transfers to S12 and output Y10 in S10 will be OFF.

Used for 1: returning to the initial step in the same step sequence, 2: jumping up/down to

non-adjacent steps in the same sequence, or 3: driving steps in different sequences. After the transition, all outputs in the previous step will be cleared.
