11 Expression Block Lab
11.1 Foreword
The Expression Block is one of the most powerful blocks and perhaps the most often used
block in MOD 30ML. This lab will provide a series of partial applications where an
Expression Block would be the best tool to solve the requirement. Enter the appropriate
expression and input names. Be prepared to demonstrate to the class your proposal for
each problem.
11.2 Objectives
In this lab you will configure 3 process applications using the Expression block. Refer to
the example given below and the reference material provided in this chapter to get more
information about the EX block.
11.3 Instructions
11.3.1 Example: Add 2 Inputs
(Note: See the end of this section for operators and rules)
1. Configure 2 analog inputs and their corresponding Signal conditioning (Input Function)
blocks as shown in the next figure. See the end of this section for additional information.
2. Configure an EX block:
• Add 2 inputs under the Inputs tab of the EX block by typing names inp1 and inp2
and data type as Floating Point.
Figure 11 .1.
EX block Example
• Type the expression: inp1 + inp2 under the Expression tab.
• Click on the Validate button to verify that the syntax is correct. See the figure
below:
