7. pArAmeter promotion
Another important step of the instrument configuration is due
to the possibility to create a custom HMI (interface) in order
to make the instrument easy to use for the operator and
comfortable for the assistance.
By a special procedure, named promotion, the OEM can
create two parameter subsets.
The first one is the “Limited access” level. This subset
is protected by the password programmed by [72] PAS2
parameter.
The last subset is the “Operator” set (Level1). This level is
NOT password protected.
notes: 1.
The “limited access” parameters are collected in
a list.
2.
The sequence of the “Limited access” parameters
is programmable and can be made according to
your needs.
3.
The parameter sequence of the operator level is
the same programmed for “Limited access” level
but only specified parameters can be displayed
and modified. This set must be create according
to your requirements.
7.1 pArAmeter promotion
proCedure
The limited access parameter set is a list. Before starting
the promotion procedure, we suggest to operate as follows:
1.
Prepare the exact parameter list you want to make
accessible for limited access.
2.
Number the desired parameters in the same sequence
you want to have in the limited access.
3.
Define which of the selected parameter will be available
in Operator level also.
example:
I would like to obtain the following limited access list:
•
OPEr - Operative mode selection;
•
SP - first set point;
•
SP2 - Second set point;
•
A.SP - Set point selection;
•
AL1 - Alarm 1 threshold;
•
AL2 - Alarm 2 threshold;
•
Pb - Proportional band;
•
ti - Integral time;
•
td - Derivative time;
•
Aut.r - Manual start of the auto-tune.
But I want that the operator to be able to change: the
operative mode, the SP value and the AL1 value. In this
case the promotion will be the following:

Now, proceed as follows:
1.
Push the
button for more than 3 seconds.
The upper display will show
PASS
while the middle
display shows
0
.
2.
By
and
buttons set a password equal to
-81
.
3.
Push
button.
The instrument shows the acronym of the first
configuration parameter group
]
inP
.
4.
By
button select the group of the first parameter of
your list.
5.
By
button select the first parameter of your list.
6.
The upper display shows the acronym of the parameter
while the middle display shows its current promotion level.
The promotion level is defined by a letter followed by a
number.
The letter can be:
c
: The parameter is
not
promoted and it is
present only in configuration. In this case the
number is forced to zero.
A
: The parameter has been promoted to the
limited access level. The number indicates the
position in the limited access list.
o
: The parameter has been promoted to the Op-
erator level. The number indicates the position
in the limited access list.
7.
Using the
and
buttons assign to the parameter
the desired position.
note:
Setting a value different from 0 the letter
c
will change
automatically to
A
and the parameter is automatically
promoted to the limited access level.
8.
In order to modify the level from limited access
to operator and vice versa, push
button and,
maintaining the pressure, push
button.
The letter will change from
A
to
o
and vice versa.
9.
Select the second parameter that you want to add to the
assistance level and repeat step 6, 7 and 8.
10.
Repeat steps 5, 6, 7, 8 until the list has been completed.
11.
When you need to exit from promotion procedure, push
button and maintain the pressure for more than 10 s.
The instrument returns to the Standard display.
note:
When you set the some number to 2 parameters, the
instrument uses only the last programmed parameter.
example:
In the previous example, I have set for SP2 a
promotion value equal to A3.
If now I set for SP3 a promotion value equal to
o3
, the
Limited Access list and the operator list becomes.
