Control device ​

NeuronEX provides the ability to control device through southbound driver through the following ways:

There are three ways to send commands to the device:

  • Users can write data to device on Data Monitoring page.
  • Users can write data to device via RESTful APIs.
  • MQTT Topic . Any external system, such as a cloud-based platform, can publish command data to a specific MQTT topic, and NeuronEX receives the command data from topic and sends it to the device.

Monitoring dashboard data writing ​

When the tag has a write attribute, the Tag on the data monitoring page will have a write operation. Click Write to realize control of the device. For example, modify the value of tag1 with write attribute, as shown in the figure below.

write

  • Click the Write button at the end of the tag whose value you want to change;
  • Select whether to input in hexadecimal mode, or not;
  • Enter the new value of the tag, for example, 123;
  • Click the Submit button to submit the new value.

TIP

This tag in the device must also have a writable attribute, otherwise the writing cannot be successful.

Check whether the value of tag is modified successfully ​

Open the Modbus simulator and check whether the value changes, as shown in the figure below.
