Sometimes I come across diasy-chained elements in the help files. What are they? How do you configure them? Other important things that we need to know about it?

Daisy chaining is typically used in the context of devices that interface for example via RS-485, and it refers to the fact that they share the same physical cable connection. The RS-485 cable runs from the serial gateway to the first device, where it is patched through to the next, and so on. DataMiner has to be aware of that, as it can only talk to one of those devices in a single daisy chain at a time.

In a serial daisy chain (RS-485/422) we typically use the ‘bus address’ field from the element wizard to identify a specific device on the multi-drop bus. By default, DataMiner will consolidate all communication to devices on the bus into a single TCP/UDP connection. In case the driver type is specified as ‘serial single’, a dedicated connection per element (device) will instead be set up.
