4. CONFIGURATION
T
Segment SP
Time
Grad
Case 2 - Segment time > Grad.
The set gradient reaches the segment SP setpoint before
the set time. The setpoint is maintained and the segment
change occurs at the end of the set time.
T
Segment SP
Time
Grad
Case 3 - Segment time < Grad.
The set gradient reaches the segment SP setpoint after the
set time. The segment change occurs when the setpoint is
reached.
T
Segment SP
Time
Grad
Warning! In order for the process PV to faithfully
follow the SP generated by the gradient or the set
time, the heating or cooling actuators should be
sufficiently powerful.
Set the segment time , touching the fields, and using the
virtual keyboard to enter the values. The units of measure
are the same as those set in the Base section.
Warning! If you have configured input events to
enable segments to be run, the concerned vari-
ables must have the required value. Otherwise the
segments will not run and the controller remains in
standby (WAIT CONDITION).
For each segment, set:
• SP: final setpoint value in the segment.
• Grad: gradient, that is, the "speed" at which the SP
setpoint is reached. This figure is indicated in seconds,
minutes, or hours depending on whether the time mea-
surement unit is, respectively, m:s, h:m or d:h (always

segment end
segment end
segment end
use the lower indicated pair unit of measurement).
The increase or decrease ramp is linear. Starting from
the process value (PV) at the start of the segment, the
controller increments or decreases the setpoint value
linearly so that, at the end of the set time, the setpoint
corresponds to the final SP value.
• HBBh: High range value for HBB alarm
• HBBl: Low range value for HBB alarm
• ALLh: Generic high temperature alarm value
t
• ALLl: Generic low temperature alarm value
• Group: PID group used for the segment.
HBB and ALL are two relative signals following the
OUT in the programme. They differ in that HBB stops
the programme cycle under way, while ALL is a generic
indication linked with the programme.

4.13.3.3. GETlogic configuration

The GETlogic page allows you to configure program func-
tions.
When the program is on, the functions are run cyclically
every 25 ms sequentially, from the first to the last.
t
The list shows all the program functions. If the memory
location is free (no function), only the order number is dis-
played. The selected row is highlighted in green.
The left buttons let you scroll through the list.
Right buttons allow you to:
t
• View1/View2: displays the list with the name attributed
to the function or its formal representation in mathe-
matical-logic language.
• New: lets you create a new function.
• Edit: lets you edit the function.
• Delete: deletes the function.
