What determines how fast the cMT series built-in CODESYS runtime is?

Select cMT and cMT X series devices can operate their own built-in CODESYS runtime to run PLC programs defined in CODESYS IDE. Below are some baseline metrics that can help explain how fast the cMT series’ built-in CODESYS runtime is:

It’s important to note that these metrics do not necessarily determine how fast a project developed in CODESYS IDE will execute on the cMT series. Execution speed will depend heavily on a variety of factors such as:

• Task configuration of the CODESYS projects
  • Number of POUs called by a task
  • Execution type of the task (Cyclic, Freewheeling etc.)
  • Task priority
• Complexity of POUs being executed
• Blocking/non-blocking behavior of POUs in Tasks

It’s important to consider the overall structure and design of a CODESYS project, as well as the complexity of individual POUs that are called in the project’s tasks. Small optimizations or more fleshed-out programs can significantly improve the execution behavior of a project on the cMT series.
