I have attempted to search the forum but cannot seem to find an answer. I am using MQTT to connect to a PLC and have numeric data (reals) coming into ignition and have placed a numeric display, in a window, in the designer. I have noticed that if I am changing the data in the PLC at 1 S/s then my numeric display updates in sync with the PLC. However, if I change the data in the PLC to update at 10 S/s, then my numeric display does not display at the same rate when comparing to the live data in the PLC.
I thought scan classes might be the solution, but I believe that is for polling type connections. Is there something I am missing or is the HMI display just going to always be slightly slower?
