5.18.1. Defining parameters recipes
Parameters recipes are defined so that the user can compile
a list of N parameters (with N ≤ 25), selected from all of the
parameters provided by the controller, and assign each one
up to 5 values.
When the user has to use one of the five groups of parameters,
he/she can select the recipe and load it in memory.
The parameters recipe list is defined in GF_eXpress by:
• the GF_eXpress RECIPE EDITOR wizard, “Template”
tab (recommended);
• the GF_eXpress “Recipe template” menu by assigning,
in the “Name”\”Value” column, the IPA of the parameter
to be added.
Parameters values in the nth recipe will be set:
• in the GF_eXpress RECIPE EDITOR wizard, Recipe_x
tab (recommended);
• in the “RECIP_X” submenus of the GF_eXpress “RECIP”
menu.
The RECIPE submenu on the configuration menu will
show only the values contained in the recipes (Read Only
parameters).
You can run a check of correct configuration of
the Recipes template by clicking the

icon in
GF_eXpress (or the “Check user recipes template
coherence” command on the GF_eXpress Service
menu).
5.18.2. Setting the active recipe
The active recipe is set by:
• parameter REC.AC inserted in the User menu;
• digital input function;
• Logic Function Block function
The recipe is loaded after every change of parameter REC.
AC (directly by the parameter, by digital input or by Logic
Function Block).
Congruity between parameters in execution on the controller
and recipe parameters is checked during loading.
If a value is rejected, the fault is signaled with a clear scrolling
message that cannot be changed by the user (“Error on
recipe 1”, “Error on recipe 2”, “Error on recipe 3”, “Error on
recipe 4“ and “Error on recipe 5”).
Exampled of setting from digital input and LFB
if the Parameters recipe function RECP.N >= 2 is enabled:
REC.0 = Select parameters recipe bit 0
with RECP.N=2 select recipe 1 or recipe 2
with RECP.N=3 select recipe 1…recipe 3 bit 0
with RECP.N=4 select recipe 1…recipe 4 bit 0
with RECP.N=5 select recipe 1…recipe 5 bit 0
if the Parameters recipe function RECP.N >= 3 is enabled:
REC.1 = Select parameters recipe bit 1
with RECP.N=3 select recipe 1…recipe 3 bit 1
with RECP.N=4 select recipe 1…recipe 4 bit 1
if the Parameters recipe function RECP.N >= 5 is enabled:
REC.2 = Select parameters recipe bit 2
with RECP.N=5 select recipe 1…recipe 5 bit 2
5.18.3. Saving parameters in active recipe
You can save values assigned to recipe parameters in
the active recipe (shown in parameter REC.AC) by using
parameter REC.SV (settable on the User Menu and by GF_
eXpress).
5.18.4. Copying recipes
With GF_eXpress, you can also copy the contents of one of
the 5 recipes to the other 4 (from 1 to 4), by clicking:
• the icon

• the “Copy Recipes” command on the Service menu
You will see a form on which you can select the source recipe
(single) and the destination recipe(s).
