Behavior of the logical outputs if they are written in different tasks.

Q: Behavior of the logical outputs if they are written in different tasks.

Goals and Symptoms Behavior of the logical outputs if they are written in different tasks. Causes and Fixes If local logical outputs are written in different tasks of the LMC (Auxiliary task, Motion task or event task) inconsistencies between the programmed value and the physical value of the output can occur. - This behavior appears if the same output is written in different tasks but also if 2 different outputs are written in different tasks. - This behavior is common to all the platforms running with Codesys and is not regarded as misbehavior. - It cannot be modified - Solution: use LMC_ExplicitOutput FB if you need to write logical outputs from different tasks of the LMC.

Causes and Fixes

If local logical outputs are written in different tasks of the LMC (Auxiliary task, Motion task or event task) inconsistencies between the programmed value and the physical value of the output can occur.
- This behavior appears if the same output is written in different tasks but also if 2 different outputs are written in different tasks.
- This behavior is common to all the platforms running with Codesys and is not regarded as misbehavior.
- It cannot be modified
- Solution: use LMC_ExplicitOutput FB if you need to write logical outputs from different tasks of the LMC.
