Device Control

Step 1 Change the value from the dashboard

When the tag is set with the write attribute, the Tag of the data monitoring interface will have a write operation. Click on Write button and input a value to control device. For example, modify the value of the 1!40001 point address with the write attribute, as shown below.

• Click on the write button at the end of the label to be changed;
• Select whether to input in hexadecimal format, not select;
• Enter a new value for the label, e.g. 123;

• Click on the Submit button to submit the new value.

  tip This point in the device must also have the writable attribute, otherwise it cannot be written successfully.

Step 2 Check whether the device point value is modified successfully

Check over the Modbus simulator whether the point value has changed to the same input value as above.
