E5EK-T allows you to configure programs made up of a maximum of
four patterns (pattern 0 to 3).
The number of steps (16 maximum) in each pattern can be specified in
parameters.
Pattern 3
Pattern 1
Pattern 0
Step 0
• Generally, the "time setup method" is used to configure programs. By
this method, set points at each step and time are used as program ele-
ments. However, the "ramp rise rate setup method" can also be used.
By this method, the set point, ramp time and soak times are used as
program elements.
• Generally, the target patterns are specified before the program is
executed.
• In parameter setup, you can specify repeated execution of the same
pattern (Repeat) or consecutive execution of all patterns 0 to 3 (Run
all).
• During program operation, steps can be skipped (Advance) and the
control monitoring can be paused (Hold).
• When the wait width is specified in parameter setup, the program
does not go to the next step and waits until the PV reaches the speci-
fied time (wait width) at the end of each step.
• Alarms that are assigned as outputs operate referenced to the alarm
values preset to each pattern.
• Time signals, program end and stage output can be output according
to output assignment.
• ON/OFF signals are output as time signals according to the timer
that takes a specified step as its start point.
