4.3.4.4 Auto variable setting#

Variables can be automatically set by converting the global variable information exported by Sysmac Studio to a text file into a specified format and reading it.

1. Convert the global variable information exported by Sysmac Studio to a text file with the following column information:

   • HOST
   • NAME
   • DATATYPE
   • ADDRESS
   • COMMENT
   • TAGLINK
   • RW
   • POU
   Example

   HOST    NAME    DATATYPE    ADDRESS COMMENT TAGLINK RW  POU
           b_test  BOOL        test1           TRUE    RW  
           i_test  UINT        test2           TRUE    RW  
           s_test  STRING(256) test3           TRUE    RW  
   

2. Press [Auto variable setting].

   

3. Select the prepared text file.

4. The variable is automatically set based on the file.

4.3.5 MQTT Collector#

This component collects JSON data using the MQTT protocol.
This component subscribes to a specific topic name in MQTT. It parses the received data as JSON data and registers the content as collected data.
The format of JSON data that can be received is the same as that of JSON serializer output.
In addition to connecting with the regular MQTT broker, it can also connect with AWS IoT Core.

1. Open the settings screen for the registered MQTT Collector.

2. Press [Test].

   

3. Test connection is attempted with the specified destination, and the result is displayed at the bottom of the settings screen.

   

4.3.5.4 Format of received data#

The format of the data received by MQTT Collector is compatible with the JSON serializer. Check the output data items of the JSON serializer.

    $ mosquitto_pub -d -h 192.168.1.10 -p 1883 -t "topic" -m '{"records": [{"data1":1, "data2":"Hello,World"}, {"data3":[111,222,333], "data4":3.14}]}'
