Detects the use of object-oriented features, such as function block declarations with
EXTENDS and IMPLEMENTS, or property and interface declarations. This rule is useful when you write code
that is intended to be ported to other IEC 61131-3-compliant systems.
Justification: Not all systems support object-oriented programming. The code is more easily portable without object-orientation.
Importance: Low
Example
//Function block extended by another and implementing an interface: FUNCTION_BLOCK POU EXTENDS CTD IMPLEMENTS ITF //SA0119 ... // Declaration parts of property methods assigned to a function block: POU.Prop.Get //SA0119 POU.Prop.Set //SA0119 --> SA0119: Object-oriented features not allowed
