4.13.1. What is a Program
A program consists of 3 macro functions to manage a pro-
duction batch in its entirety.
The 3 macro functions are:
1. Setpoint profile generator.
2. Control logic (GETLogic).
3. Batch reports.
A setpoint profile is a set of segments, each characterised
by several parameters, which allow you to adjust the value
of a process or a device as a function of elapsed time, of
specific conditions and reference values stored in the con-
troller or that are supplied from the outside.
In its most basic form, a segment consists of one step. It is
possible to create profiles made of segments with a double
step, which are shown in the graphics as two separate
lines. In this case, we have:
•
a ramp, meaning a variation in a more or less long time
of the setpoint value;
• an optional permanence, meaning a period of time
in which the process value, after having equalled the
setpoint value, is kept constant.

A program may be composed of a maximum of 50 seg-
ments and the controller can store up to 200 (model 2850T)
or 250 (model 3850T) programs.
Each program is defined by the name that is assigned to it.
The program can be controlled using the display, buttons,
digital inputs from events (Function Block outputs), or com-
mands from the custom pages. For a detailed description of
the commands, refer to “13.1.3. SP Programmer” on page
161
4.13.2. Loading and selecting the program
This tool provides up to 8 slots (4 for the 2850T), where you
can load, edit, and execute programs. The default is only
1 visible slot. To change this setting, refer to ““Controller
model” SETUP” on page 80. The position in which the
program is loaded serves as reference for all the related
commands. For example, the program in position 3 can be
started using the START_3 command. For more information
on the commands, refer to “13.1.3. SP Programmer” on
page 161
To select a program just touch its name in the list on the
display. The background becomes green.
The selected program is the one on which all subsequent
operations will be carried out (editing, closing, etc.).
If an asterisk appears next to the program name, the origi-
nal program has been modified without saving the changes.
If the user is level 2, the screen changes and additional
buttons appear. Button visibility may be conditioned by the
appropriate parameters in the SETUP\SETUP MGR\3850
SETUP page.
The buttons that appear are to:
view the Monitor Program page (see page
36);
access the selected program configuration
pages;
close the selected program and delete it from
the list;
read a program from the disk;
create or duplicate a program.
