5.2 RUNNING THE RECIPE APPLICATION
To run the (simulated) recipe application and try out some of instrument’s recipe features, do the following:
1
Download the saved modified ‘simulation’ strategy file to the instrument’s E: drive. (Only the .dbf file is required
by the Instrument).
Note If you need help with downloading, see Chapter 1, Getting started.
2
In the Instrument, load and run the simulation recipe application. After a delay the ‘pidloop’ group display
appears, containing the single ‘pid’ faceplate representing the PID control block, exactly as in Chapter 2 for the
PID loop application.
Note If you need reminding, Chapter 1, Getting started, describes how to select and run applications.
3
Press the Down key until you see the pidloop horizontal trend display. This should show a pair of black traces
representing the PID high and low absolute alarm levels — which you set to 80 and 20% respectively. The loop
will be in low absolute alarm because PV is currently zero (the green trace at the bottom of the trend).
5.2.1 Creating a recipe set
You will now create a very simple recipe set consisting of (initially) three recipes for a ‘mixing vat’. The vat is to
maintain its contents at any one of three temperatures.
To create the recipe set in the Instrument:
1
Press the Menu key, then RECIPE, or simply press the grey blank box at the top-left of the screen, the ‘recipe
pane’. In the Recipe popup, press RECIPES to see the Load/Save Recipe page.
Note The recipe options appear because you have configured a RCP_SET block in the running application.
2
Press the CREATE button, then the File Name field in the CREATE AS... popup. Type in the filename
‘MIXERS’ and press return. OK your entry. A recipe editor table entitled ‘MIXERS’ appears. The first column,
headed RCP, will contain the variable names in this recipe set, and the remaining columns will specify the
particular recipe values assigned to each variable. Each column represents a recipe in the set, and the first one is
named recipe ‘1’ by default.
3
Press the RCP column heading. It turns yellow and pops up a recipe file properties dialog showing recipe set
filename, version, edit details, and a Timeout value of 30 seconds (default).
Note Version is incremented each time the file is saved. Timeout lets you specify the maximum time allowed
for the successful download of a recipe, before the download aborts and a warning is displayed.
