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.

1. Click on the write button at the end of the label to be changed;
2. Select whether to input in hexadecimal format, not select;
3. Enter a new value for the label, e.g. 123;
4. 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.
