Single Loop Template Lab

3.1 Foreword

Many processes involve flow control loops, whether they are in the food, pharmaceutical,

chemical, pulp & paper, mining or virtually any of the industries served by MODCELL

Multi-loop Processors. This lab is designed to help you learn simple PID loop

configuration from the MOD 30ML front face.

3.2 Objectives

In this lab we will design a simple flow loop with a 4-20mA signal from a dP transmitter,

a square root extractor, a PID control loop and a modulating control valve. The P&ID for

this loop looks like this:

After completing this lab, you should know how to configure a MOD 30ML database

using ViZapp Configurator for a simple PID Control loop.
