4.4.6 Example of sequence operation settings
The following describes the steps for setting a new sequence operation, based on the sequence transition
example described in Table 4-12. The time unit is seconds (s). (
See “5.6.5 Time unit setting”
to change the time unit.)

Since jump step = 2 has been set at step 4, a jump to step 2 occurs after step 4 is completed (<1> in Figure
4-13). At that time, a conflict exists between the step 2 settings, which are for both DC voltage value
(25.0 V) and DC voltage operation type (kept at 50.0 V), but since the operation type setting always takes
priority, only the DC voltage value = 50.0 V is valid.
Since jump times = 1 has been set, when step 4 is again completed after the jump, control switches to step
5 (<2> in Figure 4-13).
At step 5, step time = 0.2 s and DC voltage value = 100.0 have been set, but when trigger input occurs this
step control is transferred to step 6 (<3> in Figure 4-13).
