With CODESYS Static Analysis, a check of the IEC source code can be performed using defined rules, naming conventions, or metrics. As a result, indications of possible development problems are highlighted and errors can be identified and corrected before a field test. This can save a lot of time during application development and error checking.

In CODESYS Static Analysis, more than 100 rules (some of which can be parameterized) are already implemented.These rule can be combined to create customized rule sets. In some rules, the rule sets defined in "PLCopen Coding Guidelines" are included. You can also define a naming convention for each possible data type, which is then checked for compliance. Furthermore, more than 20 metrics are available which, if calculated regularly, can analyze the underlying source code and provide indications of negative trends and deviations from quality targets.
