15 Totalizer Display Lab
15.1 Foreword
In many process control applications, indication of a totalized variable is required. The
user may also wish to operate the totalizer from the front panel. This lab uses a totalizer
and display to examine some of the elements of custom display building.
15.2 Objectives
In this lab, we will add a totalizer block to the database and construct a display to view
and clear the total value from the front panel. Make sure you have a database loaded that
contains a PID block and associated DISP block.
15.3 Instructions
A - LOAD A TOTALIZER BLOCK
Step Procedure Comments
1. Make sure your PID block is visible on the screen.
2. From the Algorithm library menu, select TOT
(Totalizer)
3. Drag the box onto the screen and fix it in place by
clicking the left mouse key. Move and size the block
so it is in an appropriate area of your screen. You should now have a block on your
screen called TOT.
4. Open the Totalizer block. Set the Analog Input to 1
as shown.
Because there are no actual inputs
connected to the controller we will totalize
an internal constant. Normally there
would be an external connection to
another block, such as the PVI from a PID
block.
5. Click on the Initial/Restart tab.
6. Change the Initial Mode to Run The Totalizer will begin totalizing the
