CODESYS Profiler - Article no. 2101000004

With the CODESYS Profiler, software engineers and application developers can perform an early measurement and evaluation of the processing times and code coverage of the different POUs in an IEC 61131-3 application. These measurements can be performed on the CODESYS SoftPLC or a physical device without changing the IEC 61131 application code in the project. Application development and measurement can be done in parallel in one and the same development environment.

Functionality

Dynamic measurement by instrumentation of code upon each function entry and exit after activating the runtime measurement in the development environment

Only during measurement: temporary code increase and prolongation of runtime by 10-50% dependent on PLC platform and program structure

Starting measurement via variable or on command

Clear presentation of measurement results on the development interface

Benefit

Performance and code coverage measurement of the machine code already at the beginning of the development phase

Timely notice of runtime issues

Identification of time consuming program parts and the portion of unprocessed statements

No modification of the application code by the user needed for measurement

Collective or single measurement of application POUs possible

Determination of code efficiency by comparing historical and current measurements

Improved software quality
