Multiple SFB in SCL

Hello ALL,

I wonder if there is any solution for creating an SCL FB in which I can declare SFB timers as array.

By this, I mean and wish to have just one DB UDT with all the IEC timers that I needed in the program.

Calling ex. Motors FC (in which motors are as array), the Motor[‘n’] will call and use timer FB TON[‘n’].

Thank you All,
Voicu

SFB (or FB) declarations cannot form part of an array. What you can do is declare an area in your UDT that mimics the interface area of an SFB and then set up DI and AR2 according to the position in the array and call the SFB indirectly.

I realised now, testing, that it can't be defined as an array. Could you tell me or post an example of what you said with DI and AR2?
thx

Here's an example of how to call an FB but manually setting up DI and AR2, exactly the same methjod would apply if you wanted to call a SFB
