//contains properties: Prop1, Prop2
//contains properties Prop3, Prop4
FUNCTION BLOCK FB_1 IMPLEMENTS Interface1_ITF
FUNCTION BLOCK FB2 EXTENDS FB1 IMPLEMENTS Interface2_ITF
My question is, when I go online with a project, in FB_2 I will see the properties from the first interface twice
I don't understand why. I should see Prop1 and Prop2 because FB_2 is extending FB_1, and I should see Prop3 and Prop4 because it's implementing Interface2_ITF. Why are Prop1 and Prop2 shown twice?
