All Irinos boxes are automatically addressed after switching on. The master box always has the address 0. The slave boxes are numbered consecutively in the order in which they are connected. The box sequence is also decisive for the initial numbering of the measurement inputs or the digital inputs/outputs.
The following figure shows some examples of box addressing:
In order not to get a shift of the addressing in case of a system extension, it is recommended to use the first or the last box as master box (examples 1 and 2).
The duration of the addressing process depends on the number of connected boxes. Typically, it only takes a few seconds.
The first and last boxes are also determined during box addressing. Bus termination is automatically activated for both boxes.
During setup, it should be checked after switching on whether all boxes are correctly connected and thus correctly addressed. This can be done, for example, via the webserver.
