What is the process called that checks for errors after edits have been made to the ladder logic program?

The process of checking for errors after edits have been made to the ladder logic program is called verifying. This step is crucial in programming because it ensures that the logical structures, functions, and commands used in the program are consistent and correctly formed after any modifications. Verifying helps to identify any syntax errors, logic conflicts, or issues that may have arisen from changes, allowing the programmer to address potential problems before the program is run.

Verifying is typically used as a preliminary check to give confidence that the program will execute as intended once it is compiled and tested. It represents a proactive approach to maintaining the integrity of the program as modifications happen.

In comparison, compiling refers to the process of transforming the ladder logic code into a format that the programmable logic controller can execute. Testing involves running the code in a real or simulated environment to observe its functionality and behavior. Synchronizing generally pertains to aligning different components or systems rather than auditing the correctness of logic edits. Each of these other processes serves a different purpose in the programming and implementation workflow, highlighting the unique role verification plays in ensuring program reliability and accuracy.
