Structured Text Logic and Boolean Instructions | Motor Starter Interview Practice

Structured Text PLC Programming handles logical and mathematical comparators similar to other programming languages such as C, C++, Java and Python. However, their syntax may be unfamiliar to those who work on PLCs within a ladder logic environment. That being said, every branch of PLC ladder logic is a state flow that can be simplified into a logical flow thus used in a single Structured Text statement.

Structured Text Example for Input & Output Tag Aliasing Assignments

One of the ways we utilize Structured Text to speed up machine development is through input and output assignment. In a typical system integration environment, one would have to create a rung dedicated for every input and output in order to pass the data to an internal tag of the PLC. The reason for this practice was discussed in a tutorial on tag aliasing we've released before. In short, by doing so, we can easily reassign and expand our tags as the program changes.
