Ok gracias ...

Hi there. Let's see if someone can help me. I have a unistream PLC connected to a mosquitto broker. The PLC is subscribed to various topics. Everything seems to be working fine, but sometimes when I restart the PLC, it doesn't subscribe to topics. However, the connection with the broker is correct. If I see the status of the configuration tags, the following appears: Broker1.Connected = 1 Subscription1.Subscribed = 0 Subscription1.Status = -11 (this means UniStream is not connected to the broker however it is connected.) To solve this problem I have to restart the PLC again.

Hi there. Let's see if someone can help me. I have this scenario: - Raspberry pi with mosquitto broker. - Unistream connected to the broker and subscribed to a topic - Several temperature sensors as clients publishing a topic every 1 second. Everything works fine but, any idea how to know if a client has disconnected? In the client configuration I have the "keep alive" function set to 10 seconds, however the "Subscription.Subscribed" bit is always at "1".

So Praticio....how did actually DO all your "electronic, electrical and instrumentation constant learning every day"?  Did you read a Help file, consult a User Manual, or have someone hold your hand and show you all the time? What you were asking for was a LOT more than "ask for a little help", and your last sentence above is the behaviour of a 2 year old having a tantrum. Good luck.  

Que increíble.... Espero, no pases por algo así , para que no tengas las mismas respuestas que das , ya que la vida no se trata de PLC y para su conocimiento toda mi vida me he esforzado en lo que hago , soy electrónico , eléctrico he instrumentista , eso es esfuerzo y aprendizaje constante día con día , pero y siempre muestro y realizó las cosas con mucho esfuerzo , solo pedí un poco de ayuda , no que me realizaran el programa . Pero bueno ya estoy trabajando y con la ayuda de otro programador que si pudo responderme las cosas que necesitaba si se ESFORZÓ  en dar una explicación para comenzar con mi proyecto.   Gracias y que esté bien lo molesto más.
