Setting up an Output Control Switch


  • Hello All,
    First of all:
    Mango Core: 3.6.3, Mango API: 3.6.1, Mango UI: 3.6.2, Platform: Centos 7.4.1708
    Java Version: 1.8.0_161, Browser: Chrome 75.0.3770.100 (Official Build) (64-bit)

    I am in need of some advice. I am trying to set up a switch on the dashboard that will control an output on our logger. To change the Digital Output on our loggers I have to insert a row into the loggers MySQL commands table.

    Our system is set up so that the loggers all put their data into a MySQL database, Our Mango 3 uses SQL Data Sources to pull the data and then Meta Data Sources format the data into the values that are displayed on the dashboards.

    I have a settable binary Meta Data Point called control. Using the dashboard examples in the play area, I have a switch that will change the value of the control point and can view the results in the watchlist. So far so good. I need to get the value from the meta point to trigger a MySQL command in an SQL data point that is set to modify table only as shown here:

    INSERT INTO DB1.commands (id, register_type, output_number, state) values (2, 9, 1, ?);
    

    The ? for state should be replaced with the value from the Meta Data Point via a Point Link.

    If this seems to be a long way of inserting the command into the MySQL database please let me know a simpler more direct way.

    The first question I have: Why does the watchlist display the value as Off or On even with the text render set to 0 or 1. and when I validate the script, I get either True or "Success, no new value"
    Here is the export of the data point:

     {
      "dataPoints":[

            "zeroColour":"#ff0000",
            "zeroLabel":"0"
          },
          "tolerance":0.0
        }
      ]
    }
    

    The second question is about the Point Link. I have set up a point link to use the control point above as the source and an SQL data point as the target. I started with this script to test the values from the dashboard:

    return (source.value);
    

    I had stopped there to validate that I was getting the correct values from the source point.
    But again here I get either true or "Success, no new value". Not a false.

    So I tried then to create an If statement that would return either a 1 or 0 for the SQL data point that will run the Insert command. The script was:

    var s1= (source.value);
    if (s1 = true) return '(1)'; return '(0)';
    

    But this does not work. I get the following error when trying to validate:
    0_1564419371083_806b4965-792a-4df7-9550-7ea80514164a-image.png

    Any advice on how to get the MySQL command to be triggered from a dashboard switch would be greatly appreciated.

    Also my apologies if this was addressed in a previous topic but I couldn't find it.

    Cheers
    Brian


  • Hi Brian,

    Also my apologies if this was addressed in a previous topic but I couldn't find it.

    There's a few questions here, probably hard to find a thread with all of them ;)

    The ? for state should be replaced with the value from the Meta Data Point via a Point Link. If this seems to be a long way of inserting the command into the MySQL database please let me know a simpler more direct way.

    I would say get rid of the point link and add the SQL point into the context of the meta point. Some versions ago Meta points gained a .set() function on context points the same as Scripting data sources have always had. We've actually discussed converting all Point Links into Meta Points because a point link without a script amounts to target.set(source.value); and isn't much harder to convert when it does have a script. The only current different would be the Meta point's set function is run in the thread executing the Meta point, where a Point Link creates a SetPointWorkItem.

    This would enable you to set the point directly to the string you are going for.

    But this does not work. I get the following error when trying to validate:

    Thanks for bringing this to our attention. Seems to be an issue in the Point Links module. Also, you should not be doing if (s1 = true) as that is an assignment in an if statement, not a comparison operation.

    Any advice on how to get the MySQL command to be triggered from a dashboard switch would be greatly appreciated.

    I'm not certain I understand why you wouldn't set the SQL point directly from the dashboard, but perhaps my suggestion of the set function in the meta point gets you where you need to be.


  • I was not able to replicate the validation issue of casting the java.lang.String . Looking at the code it doesn't seem like that should happen. Was there a stack trace in your Mango/logs/ma.log file?


  • Hello Phil,
    Thank you for your reply, You have given me some things to think about.
    We use point links because that is what worked in Mango 2. We use them to update a flag column in the MySQL input tables so our SQL data sources know which rows have been read already.

    I was trying to use the point links to do the same job but with an insert command instead of an update command.

    I need the insert command to work with either state of the binary point. I considered setting the SQL point directly but could only work out how to set a single state that way. And that way I would need an On switch and a separate Off switch on the dashboard.

    Any coding advice on how to do this would be very helpful.

    I changed my IF statement to use === (my lack of experience is showing) but I still got the validation error.

    Here is the trace from the Ma.log that occurs when I try to validate:
