4. CONFIGURATION
A blank line appears in the window for the new segment.
Touch the individual fields to:
Give a descriptive name to the segment. The name
•
can be an alphanumeric text up to 16 characters long.
• Assign a value to SP 1, the setpoint of the 1st syn-
chronised profile.
• Assign a value to SP 2, the setpoint of the 2nd syn-
chronised profile, if it exists.
• Assign a value to SP 3, the setpoint of the 3rd syn-
chronised profile, if it exists.
Assign a value to SP 4, the setpoint of the 4th syn-
•
chronised profile, if it exists.
The step number is generated automatically.
Touch IO step in the pop-up menu to open Input Event
Configuration Window 1 that enables the segment to run.
The list corresponds to the corresponding variables set in
the Base section.
For each variable you can set:
• - : ignore the variable value.
• ON: only run the segment if the variable is ON.
• OFF: only run the segment if the variable is OFF.
To change the reference value, touch the field next to the
variable name repeatedly until the desired value appears.
If the start conditions are not met, the program remains in
standby (WAIT CONDITION).
You can switch from one segment to another using the +
and - buttons above and below the segment number to the
left of the page. You can also jump directly to a particular
segment by touching its number and entering, in the virtual
keyboard that appears, the desired segment number.
Touching button 2 at the bottom of the page, the output
event configuration window 2 opens.
The list corresponds to the corresponding variables set in
the Base section.

For each variable you can set:
• = : keep the original variable value.
• ON: assign value ON to the variable.
• OFF: assign value OFF to the variable.
To change the reference value, touch the field next to the
variable name repeatedly until the desired value appears.
Touch the CFG step button in the pop-up menu to open the
profile configuration window of the individual segments.
CH1, CH2, CH3 and CH4 correspond to synchronous pro-
files 1, 2, 3 and 4 respectively (the number of synchronous
profiles depends on the settings in Base section page 2).
As a segment run time, you can set a time (unique value
valid for all synchronous profiles), a gradient (value that may
be different for each synchronous profile), or both.
There are two times (ramp and retention) in the case of a
program with a double step, as shown in the figure ABOVE
(add number)
The configuration of the single profile can therefore be:
• Time = 0 and Grad ≠ 0: the SP setpoint for the profile is
generated following the gradient value set.
• Time ≠ 0 and Grad = 0: the SP setpoint for the profile
is generated following the set time.
• Time ≠ 0 and Grad ≠ 0: the SP setpoint for the profile
is generated based on the gradient but also takes into
account the set time, as shown below.
Segment behaviour with Time ≠ 0 and Grad ≠ 0
Case 1 - Segment time = Grad.
The set gradient reaches the segment SP setpoint in the
set time. The segment change occurs at the end of the set
time.
