The list of objects is dynamic, i.e. when a new value arrives in the KOM process, it is updated. Filtering in individual columns (with the exception of of the Time column) is is also supported, ; asterisks can be used in the mask (e.g., *Short*).
Double-clicking on a particular line will insert the value from the Address column into the configuration of the I/O tag from which the MQTT Item Browser window was opened. At the same time, it is also inserted into the clipboard.

| STCOMMAND | STCOMMAND StationName PUTOLDVAL BeginTime EndTime | For Payload Type = Edge Node: The Tell command reads out historical values of output I/O tags (if the I/O tags or their control objects are archived) and sends them as historical values. Reading works independently of the Store & Forward protocol parameter. Using this command, it is possible to send historical values even for the period when the D2000 KOM was turned off (and therefore the Store & Forward functionality could not work). Example: STCOMMAND B.MQTT_MOSQUITTO_EN.Device1 PUTOLDVAL "30-05-2025 00:00:00" "30-05-2025 00:10:00" |
