6. 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 pro-
tected by the password programmed by [114] PAS2 parameter.
The last subset is the “Operator” set (Level1). This level si
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
6.1 Parameter promotion procedure
The limited access parameter set is a list, so that, before to
start promotion procedure, we suggest to operate as follows:
1. Prepare the exact parameter list you want to make
accessible for limited access.
2. Give a number to the desired parameters using the same
sequence you want to have in the limited access.
3. Define which of the selected parameters will be available
also at Operator level.
Example: I would like to obtain the following limited ac-
cess list:
• OPEr - Operative mode selection;
• SP1 - First set point;
• SP2 - Second set point;
• SPAt - Set point selection;
• AL1 - Alarm 1 threshold;
• AL2 - Alarm 2 threshold;
• Pb - Proportional band;
• Int - Integral time;
• dEr - Derivative time;
• Aut.r - Manual start of the auto-tune.
But I want that the operator is enabled in changing:
the operative mode, the SP1 and the AL1 values.
In this case the promotion list is:
Parameter Promotion Limited Access Operator
- OPEr - o 1 OPEr OPEr
- SP1 - o 2 SP1 SP1
- SP2 - A 3 SP2
- SPAt - A 4 SPAt
- AL1 - o 5 AL1 AL1
- AL2 - A 6 AL2
- Pb - A 7 Pb
- Int - A 8 Int
- dEr - A 9 dEr
- Aut.r - A 10 Aut.r
Now, proceed as follows:
1. Push the
button for more than 3 seconds.
2. The upper display will show
PASS while the lower
display shows 0.
3. By
and buttons set a password equal to - 81.
4. Push
button.
The instrument shows the acronym of the first
configuration parameter group ]
inP.
5. By
button select the group of the first parameter of
your list.
6. With the
button select the first parameter of your list
7. The upper display will show the acronym of the parameter
while the lower 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 is present
only in configuration. In this case the number is
forced to zero.
“
A” Indicates that the parameter has been promoted
to the limited access level. The number shows its
position in the limited access list.
“
o” Indicates that the parameter has been promoted to
the Operator level. The number shows its position
in the limited access list.
8. By
and buttons assign to this parameter the
desired position.
Note: Setting a value different from 0 the letter “c”
changes automatically to “A” and the parameter is
automatically promoted to the limited access level.
9. In order to modify the level from “Limited access”
to “Operator” and vice versa, press
button and,
maintaining the pressure, press button.
10. The letter changes from “A” to “o” and vice versa. Select
the second parameter that you want to add to the “Limited
access” level and repeat steps 6, 7 and 8.
11. Repeat steps 5, 6, 7 and 8 until the list has been completed.
12. When you need to exit the 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 same number to two parameter, the
instrument will use only the last programmed parameter.
Example: In the previous example, I must set for SP2 a
promoton 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:
Parameter Promotion Limited Access Operator
- OPEr - o 1 OPEr OPEr
- SP1 - o 2 SP1 SP1
- SP3 - o 3 SP3 SP3
- SPAt - A 4 SPAt
- AL1 - o 5 AL1 AL1
