I tend to prefer encapsulating this type of functionality into a UDT. This way I can easily instantiate another “heartbeat” object when it is time to monitor another device (in this example). Attached is a tag JSON that will create the structure shown here:

You’d obviously change the _heartbeat_ tags to OPC tags and then set the address accordingly–the example here uses memory tags.
