mapp Services V5.16

The RETURN statement can be used to exit a POU (function, function block or program) prematurely.

If a RETURN statement is used in a function or function block, the program execution in the calling POU is continued immediately after the function or function block is called.

A RETURN statement in an action does not exit the POU; it only exits the action. Program execution continues in the calling POU immediately after the action is called.

Syntax

RETURN;

Example

IF Var1 < Var2 THEN
    RETURN;
END_IF;
