ST-editor reacts sluggishly.

Symptom:

The ST-editor reacts sluggishly to actions – in particular when editing the ST-code by means of the content assist or refactoring.

Cause:

The ST-editor contains nested →calls of →blocks. When the nesting depth increases, the ST-editor becomes slower.

Example
PROGRAM Program1
VAR
Var1 : INT;
END_VAR
Var1 := MOVE(MOVE(MOVE(MOVE(MOVE(MOVE(MOVE(MOVE(MOVE(MOVE(MOVE(2)))))))))));
END_PROGRAM

Solution:

  • Install version 1.28.0 (for logi.CAD 3).

  • If you are using a version < 1.28.0 (for logi.CAD 3): Avoid block calls with a high nesting depth. Declare and use auxiliary variables.

images/s/b2ic8e/9012/1ca6q62/_/images/icons/emoticons/information.svg logi.cals recommends to install and use the most current versions of logi.CAD 3 and the runtime system so that the latest features and problem fixes according to the release notes are provided in the used version.
