6-14 Applied Operation PLZ-4W
6.6 Sequence Function
Sequence is a function that automatically executes instructions speci fi ed in advance
one operation at a time. By specifying a sequence of operations (steps), various
waveform simulations can be executed. The sequence that you create is saved by the
backup function even when the power is turned off.
■
Normal sequence and fast sequence
There are two execution modes in the sequence function of the PLZ-4W: normal
speed and fast speed.
• Normal sequence
A normal sequence can be set and executed from the PLZ-4W operation panel. In
addition, the communication function can be used to set and execute the sequence
from an external controller. The execution time can be assigned to each step. You
can pause a sequence using PAUSE and resume a sequence using an external trigger
input.
• Fast sequence
A fast sequence can be set and executed from the PLZ-4W operation panel. In addi-
tion, the communication function can be used to set and execute the sequence from
an external controller. Each step is executed at high speeds. The high time resolution
allows high-speed simulations. Each step is spaced evenly, and up to 1024 steps can
be executed.
