Homogeneous ibaPADU-8AI chain
Up to 8 devices can be connected in a line topology. The outputs of the devices are to
be connected with the input of the following devices until all devices are interconnected
and the last device is connected to the ibaFOB card. All addresses (1...8) within a chain
must be unique. If 2 devices carry the same address the subsequent device in the fiber
optic link overwrites the content of the previous device.

Principle of the data packages in a FOB telegram
Each box (address) contains 8 8 digital signals. The device address determines
where the data are placed in the telegram. Therefore, the position of a device in the chain
is independent of the address setting.
