Hi community, "Could you please explain to me how the method FB_init works? The block inside it states, 'the retain variables are initialized (reset warm / reset cold).' Every time I perform a 'cold' reset on the PLC, do I need to call FB_init? Am I thinking correctly?" Then I do that VAR_GLOBAL PERSISTENT x: UINT; END_VAR Create function block {attribute 'call_after_init'} FUNCTION_BLOCK Test VAR_INPUT y: INT; END_VAR VAR output :INT; END_VAR output:=y*y; Create FB_init of function block METHOD...

Hello, I have a perhaps stupid question. I've noticed a lot of code where variables are named with an underscore. If I write it like this: VAR ValueToUInt :UINT; END_VAR AND VAR _ValueToUInt :UINT; END_VAR Is it the same or not? Is it nothing means? It is only convention.

Thank you for message. I tried do that, what you suggest to me. I create VisuInit program block I attached it. I don't understand why VisuInit program block is not running.
