  1. Thank for your reply.

    • Subscription properties -> Quality of service -> 0
    • Broker lined to the Subscription -> Clean session -> not activated

    I have tried to subscribe from another client installed on a raspberry pi and the subscription is correct.

    However, from unistream I do not have a subscription, but I do have a connection with the broker:

    • Broker1.Connected = 1
    • Subscription1.Subscribed = 0
    • Subscription1.Status = -11 (this means UniStream is not connected to the broker however it is connected.)

     

  2. 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.

  3. 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".

  4. Yes, It's Alarm Summary.

    Calling Alarm Summary is using banner. There are no  action calls from the program.

    We try to erase and recognize all the alarms and then hangs the screen but the control still works.

     This failure occurs randomly (rarely)
    I will consult my client to see if it is possible to send them the application program.

  5. I was working with a UniLogic project when the computer shut down. Reopening the project with VisiLogic gives me the following error:

    "This project was created with an later version of UniLogic, and cannot be downgraded. Please open this project with a newer version of UniLogic"

    Now I'm not able to open the project and I use the latest version available: 1.18 rev 60
