Task Configuration

The possible number of tasks depends on the CPU type. How to use the task configuration for the Automation Builder is described in detail in the chapter “Resources / Task configuration” (Link to

3S: CoDeSys Programming System / Resources / Task configuration: mainchapters/TaskConfiguration

As of firmware V2.4: For a new project a task with the following properties is created:

Type = cyclic

Priority = 10

Cycle time = t#10ms

Program call= PLC_PRG.

We recommend to create a task according to your needs.

Up to firmware V2.4: Specify a task in your project according to your needs.

All 32 priorities can be selected for the user tasks, where 0 is the highest priority and 31 the lowest. The default priority is 10.

Priorities lower than 10 are reserved for high-priority processes with a very short program execution time. The priorities 10 to 31 are intended for “normal” user tasks or tasks with a long program execution time.

Attention

Using, for example, a priority lower than 10 for a task with a long program execution time can cause, for example, the CS31 bus and/or the FBP interface to fail.

System Events

Attention

System events belong to the group of online tasks. Floating point calculations are not allowed in online tasks, for they are not rechecked via software like IEC tasks.
