BUILDING THE STRATEGY
BUILDING A WORKING TOTALIZER STRATEGY WITH DISPLAY
You must be inside a loop compound to build this strategy. It is assumed that the user of this
document has a basic understanding of Application Builder software.
The totalizer and PID parts of the strategy are relatively straight forward. We will offer two
different display options in this application document.
If your Application Builder is version 5 or newer the Compounds directory will offer two
PID/totalizer display compounds (PIDTOT1.CSM and PIDTOT2.CSM). Both compounds include
a single loop PID and totalizer function. PIDTOT1.CSM uses one display tag for the PID,
totalized value and totalizer command functions. This functionality is probably the most common
display used for a PID and totalizer application. PIDTOT2.CSM places the PID and totalized
value on one tag display and the totalizer command functions on a second display tag. If you
don’t find these compounds, the following instructions will help you build the PID, totalizer and
display(s) from scratch.
APPLICATION 1 - TOTALIZER AND PID
This first application will include the totalizer display and its command functions on the same
display tag as the PID display. This is handy because the operator does not have to leave the
PID display to see the totalized value or to use the totalizer commands.
Placing The Blocks & Making Connections
As a shortcut we will be loading a direct connect PID loop compound from the compounds library.
This compound already includes a basic single loop PID with input and output blocks, display,
alarms and a tune list blocks.
1. Select the Compounds icon using the right mouse key.
2. From the sub-menu select the Load icon .
3. Select the COMPOUND directory.
4. From the COMPOUND directory select the compound block file entitled BASICPID.CSM.
5. Press OK.
6. When asked to save occurrence numbers, say No.
7. You should have a blue Direct Connect Compound on your PC screen. Double click on the
compound to open it.
Adding a totalizer block to the compound.
1. Select the Library icon from the top of the screen.
2. Select ALGORITHMS.
3. On the left side of the screen, from the algorithms menu select and drag to the work area a
Totalizer block .
