    Hi,

    In my case, I used multiple MB_client function blocks to read data. I was using the same client ID for all of them. I changed the connection ID of those differents connections and the problem was fixed.

    if you have 3 instances of MB_client. you must set unique connection ID per instance

    Example:

    ID = 1  for MB_client_1 instance

    ID = 2  for MB_client_2 instance

    ID = 3  for MB_client_3 instance
