How do I call a ST program from another ST program passing parameters


These sample programs are intended to demonstrate one or more programming functions or methods and are presented as programming examples only. Schneider Electric assumes no liability for the use or application of these example programs or any portion thereof.

Sometimes it is necessary to call one Structured Text logic program from another one.

The attached example shows how to do that.

Just import the attached SDE file and look at the code inside ST1 and ST2.

ST1 calls ST2 passing a string as parameter. ST2 uses that parameter to query the database and returns a result.
