Issue
What is the size limit of a Structured Text section in Unity Pro?
Product Line
EcoStruxure Control Expert (former Unity Pro)
Environment
Unity Pro v12.0
Resolution
The length of a Structured Text instruction line is limited to 300 characters.
The length of a Structured Text section is not limited within the programming environment. The length of an ST section is usually limited by the size of the PLC memory.
NOTE: There is no size limitation for section, but sometime when using a large amount of literal assignments or some specific instructions, a section can generate a Code generation failure during an application build. Then the solution is to split the section in two or more sections to build the application.
