Hi,
I am using a simple blink example with a redundant application. I wish to send a stream on each individual FB and wished to see if there was a way to identify them through the code. for example, I want to check if the FB is E_SWITCH then perform some task, and then check if the FB is E_SWITCH_1 and then perform something else. Is there a way to do so?

hi,
can you please expand a bit on what you mean with sending a stream on each individual FB?
Regarding the identification of individual FBs: In 4diac FORTE each FB type is a class and each FB instance will be an instance of this class. In the C++ code you can access the instance name of the FB and us that for identification.
If you would like to get event streams a hook can be the code in the CFunctionblock base class where input events are received and outputevents are sent.
I hope this is in the direction that you asked.
BR,
Alois

Ah thanks for the clarification. IEC 61499 states that FBs are encapsulated and they will behave the same independent to whom they are connected. Given your setup I think it would make more sense to have a dedicated configuration parameter as part of your receiving layer (I think it is also better to not modify our udp receiving code but have a dedicated layer on top which handles that, I remember Mario de Sousa had a nice paper on that topic). Or if that is not what you want better check on resource or devices. Although I think the first option is better configureable by the user.
