When using a tag as an indirect tag, if you copy a normal tag, the copied tag will be assigned.
By using indirect tags, multiple tags can be monitored/controlled for the same purpose.
< Example screen using tags as indirect tags in a project >
If you write a script as shown above, the indirect tag $FLOW will be changed to the same value according to the state value of the $DEVICE1_FLOW tag.
You can create a single graphic screen to monitor/control the status values of the same device and display each status.
Please refer to the example by selecting "File | Restore" from the text menu in the task selection program.
